Using intercepts and the maximum, find an equation for the graph shown.
a) f(x) = 3x2 + 6x - 9
b) f(x) = 3x2 + 6x + 9
c) f(x) = -3x2 + 6x - 9
d) f(x) = -3x2 + 6x + 9

what is the original number? you forgot to add it.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
