# Math Help - Need some major help!!! i'm about to go nuts~

1. Gosh, I feel so darn stupid.....

All i have different is the numbres. I've plugged them in the problems u helpped me with and still cannot get them right...

"For the quadraic function f(x) = 5.71x^2 -3.135x -5.64, find the maximum or minimum value, the x-intercepts, and the y-intercept."

I guess I'm going to spend hours on end heere trtying to understand it. I have 4 HW assignments and 3-4 tests due next week. I need help despirately

2. I ALMOT GOT IT!!!!!

how do i find the y intercept? what i hjave is wrong, i almost have it tho

3. The y-intercept can be found when you plug in (x=0).

what is $f(0)$? That's your y intercept.

$f(0)=5.78(0)^2-3.135(0)-5.74=\dots$
