Question

f(x)=-x^2+10x^2

Answer 1

and?

Answer 2

9x^2

Answer 3

I need the vertex please

Answer 4

x = -b/2a

Answer 5

how -b/2a

Answer 6

u hav to write this in another form.

Answer 7

Completing square form.

Answer 8

x,y

Answer 9

sumwhat

Answer 10

thats not it

Answer 11

Yeah, I just noticed

Answer 12

Saifoo is right. you have to subtract first to get 9x^2

Answer 13

Which means you b = 0

Answer 14

Which means that x,y = 0,0

Answer 15

10x^2 - x^2 = 9x^2

Answer 16

thats not it

Answer 17

Find the vertex, the line of symmetry the maximum or minimum value of the quadratic function, and graph the function

Answer 18

(0,0) is the correct vertex and it is a minimum value. The line of symmetry is x = 0. If you graph it, it will be concave up with the vertex at the origin. What's not right about it?

Answer 19

A quadratic doesn't have to have three terms

Answer 20

thats not it

Answer 21

it is says (5,27) was the anwser

Answer 22

was the negative in parenthesis: (-x)^2 ?

Answer 23

thats not it

Answer 24

I am so sorry I did not put the problem up I am sorry I wrote it wrong sorry to waste ur time on there

Answer 25

thats not it

Answer 26

it was +2 instead of ^2

Answer 27

I see

Answer 28

can you re-write it the correct way please?

Answer 29

thats not it

Answer 30

-x^2+10x+2 sorry

Answer 31

so that means if you use x = -b/2a , you will get x, which equals 5. and if you plug x = 5 into the function you will get 27
