Okay, So the first part of this question is asking goes to find the It's asking us to find a maximum minimum value off the function by using, um, take you to the capital it or you can use a graphical device. Averages like calculator. Um, I'm using the Casio FX 89 one on 991 the X right. So if you just type the equation into the it's gonna be different for every capitalist. It's hard for me, too. Have you along with this right now. But just ask him, your tutor. Are your teacher how to do this on your particular device? Maybe that you need to get any device? I'm not sure, really. Well, it's always good to investing in the conflict that could do something. So put this into your calculator. Um, why get at the minimum values? I get minus full point and asked us to round 22 decimal places. I get minus 4.1 I'm to two decimal places, all right, and in part be asked you to find the minimum minimum or maximum value. Um, without doing that, Andi. Okay. So the way I'm gonna find a map terminal with values. I'm actually gonna use the maximum long We've been value equation to find the ex corn Vertex, and I'm gonna die. So the ex corner of the Texas with minus B over to a here and that's going Thio equal minus 1.79 over two tires by one, slashed over too. I put them to my calculator. I don't want to be rounding a tall here because that, uh, I'll reduce the accuracy of my answer. I get just minus 179 over 200 I could just keep it. Is that for the moment? And then I'll stop that back into the equation, and I'll see what that gives me. So, my ass. 179 over 200 All square plus 1.79 times by 179 over 200 minus 3.2 won't. So when I put that into my calculator, I'm just doing that now. My thoughts of nine over 200 all squared, plus time to buy matter for some night, too. Um, my realistic. What you want? I actually got saved by, um, yeah, not quite sure what it's getting on. Yeah, I got the same value of 22 decimal places on some calculators. Um, it may be different book here. My calculator got minus 4.1 on when I worked out using the phone. When I go, I've got minus 4.1 to 2 different places. Um, so I know I'm kind of interested. Um, yeah, if you got a different answer, if you got any questions about on this particular exercise just evenly at Daniel Doggy patched up Nolan actor Jima that come. Thanks very much for listening. And I wish you the best for your studies.
