Question

Find the maximum or minimum of the following quadratic function: y= X^2-16

Answer 1

^2 representing exponent 2 and the answers are

A: -16
B: 16
C: 32
D: 48

Answer 2

I think it's -16, if they're looking for the vertex.

Answer 3

If not, then I still need to keep looking.

Answer 4

What's the derivative?

Answer 5

So I put the numbers into the A and X spot, right?

Answer 6

Don't worry, It's -16

Answer 7

Oh thank gosh, I came up with that earlier, I was thinking this was about to get much more complex.

Answer 8

So -16 is the answer?

Answer 9

At first, I thought you are studying maxima and minima.
here is the graph plotted , https://mathway.com/
you can notice clearly that "-16" is a minimum point.
