The graphs of $f$ and $g$ are shown. Find the function values for the given values of $x$, if possible. a. $(h+k)(-1)$ b. $(h \cdot k)(4)$ c. $\left(\frac{k}{h}\right)(-3)$ d. $(k-h)(1)$ e. $(k \circ h)(4)$ f. $(h \circ k)(-2)$ g. $h(k(3))$
Okay, so we're takes one with a bearable sq. And by why is it called a X minus? Edgell square Bless gay and your war Dixie's H G. Right? A year HK is in the forest, Gordon. Right. So as you can see here, option to a similar raise our function. Right. So you're edge and gave. Both are positive, which means HP allies under for squint. But here, ace positive, which means our venerable opens upward so we can draw a bearable are like this You're vortex is in the first Cortland, right? And you're edge and gave Both are positive, right? So as you can see, your graph of the function does not intersect the X axis. Right? So here we have a no X intercept, Right? So where that option B is correct, we can right here for the unction. Be hopes and bees Correct? No. Or the function A As we can see here, x co ordinated off the world ex is negative. So, here or taxis Negative Ridge and Katie and it here parabola opens downward because you're aces. Negative, right? So we can draw a bearable like this. You're excluding it off the war Texas negative in your case before they do right? And you're parabola opens down because he's less than zero. Right? So your war takes is in the second cordant right in here. We have two x intercept, right? So your absences correct for the function A hopes and sees correct now for the function. See here edge beast Positive and a skirted zero. Right. So we're more Texas negative, risky and your ace credit. And zero, which means bearable one support so we can draw their function like these year or take ceased negative. Bridgegate in your parable opens upward, right? Because here, do you A Z equals zero. So for the function, see here obscenities correct, Right, Because you're really no x intercept. So for now, thanks and see what's Cindy's correct land for the remaining function D Nearly every many option a. So that is to your correct answer. Thank you
Here we have three graphs. Each of them is according to F of X equals X squared plus K and figure out OK is for each of you are going to start with. The green ones are gonna do a green green. Oh, so essential is okay. Just like what linear equations is. Our Y intercept becomes when we do X squared of zero physical zero. So at 00 this should be called zero. Well, here were it to soak a has to to to, But the red one. We have the same idea we do after zero. Well, zero plus can K has to be equal to once. Okay, Last, Like for the blue one. Same idea. F zero people. Zero plus k is negative. Three years. Okay, has people too? Negative was there are many answers.
Because if we're this problem, because I'm plugging in 12 and three for acts, I consider each road to be what, up again for acts. So we'll get him one on one. Squared is one are coefficients would just be 111 Plugging into my coefficients for A B and C would be 4 to 1, and plugging in three will be 931 sense of my inverse matrix. For this, it's gonna be equal. Teoh 0.5 negative 10 point pyre. We're gonna have negative 2.5, uh, four and negative. 1.5. We're gonna have three negative three and one. Okay, So for part A, we're gonna have a inverse at times R K values. Okay, values for part air. Negative to one in six. Okay. And so my A, B and C values will be in order from top to bottom we're gonna get and a body of negative three B value of zero and see value of one. Okay, So for part B were and do the same thing. We're gonna change our K values to 43 and negative too, can't updating. There's it's gonna give us an ABC value of one five and negative too. Okay. And then part C. We're changing those K values, too. Eight negative. Five and four. It's a changing those. We're gonna have eight five, negative four. Okay, so our ABC values will leave five, six and negative three. Okay. And using these three points, this is pretty much exactly how quadratic regression would work if you're using three points. So this is also what quadratic regression and a calculator would give you Okay, for A B and C So again A B and C from top to bottom. Thank you very much.
We need to find following coordinate points. So letter G. We went to to the right and one up H. was at the origin so that 00 I we went, oh oops, this is I I we went four to the right, three down Jay. We went four to the left, zero up and down. Okay. We went to to the left And then three up let her out. We went zero right and left, but five up.
