Question

I just need help to figure out if I got an answer correct. The problem is f(x)=-x^2+6x+27. The x coordinates of the intercepts (I got) x=-3,0. The y intercepts (I got) 0,0. Which means there is no intercept for y.

Answer 1

I am taking an online quiz and can't go back and change my answers so any help would be great!

Answer 2

Hang on a minute.

Answer 3

ok thanks

Answer 4

I got 9 and -3 for x intercepts and 27 for the y intercept.

Answer 5

Let me graph it and see.

Answer 6

So where did I go wrong? hmmmm.

Answer 7

ok

Answer 8

To find the x intercepts, replace y with 0 and use the quadratic formula. 9 and -3 and the correct x intercepts.

Answer 9

To find the y intercept replace x with 0. You will bet 27 for the y intercept.

Answer 10

get not bet

Answer 11

the quadratic formula is -b+/-sqrt(b^2-4*a*c/2a?

Answer 12

yes
