Question

If f(x) = x + 3, find the value of x if f(x) = 9.

Answer 1

Set f(x) equal to 9.
9 = x + 3
Can you solve for x?

Answer 2

Plug in 9 where the x is. 9+3 =12

Answer 3

f(x)=x+3
since f(x)=9 so,
9=x+3
x=9-3
x=6

Answer 4

@IStutts You are incrorect. It says FIND x if f(x) = 9. Not find f(9).

Answer 5

so its 12

Answer 6

No. I just said that @IStutts was incorrect.

Answer 7

so 6

Answer 8

yup you got the right answer
