Answer 2

do you know how to find the equation for this function?

Answer 3

no, not really...

Answer 4

ok... well just looking at it then.... there's a minimum y value of -9

Answer 5

but the maximum y value... as its a parabola there isn't one

Answer 6

also with the x values.... its a vertical parabola.... so it appears to continue out both left and right to infinity... so no maximum or minimums there

Answer 7

so... the answer is (-9,∞)?

Answer 8

well... no, that's kinda more how you write coordinates
(x,y)
and the min y value is -9... not the mix x value

Answer 9

....i'm confused now...

Answer 10

well... if you were going to write it as a a coordinate... the coordinates for the minimum y value are ( 3, -9 )
other then that, there are no minimum x values or maximums

Answer 11

i'm still confused on the subject a bit, but you've helped me. thank you.
