Question

Let f(x) = 9x - 2 and g(x) = -x + 3. Find f(g(x)).

Answer 1

Replace the x in function f with the expression for g. Then simplify.

Answer 2

does anybody know how to do it ^^

Answer 3

okay thank you

Answer 4

f(x) x = 2/9 g(x) x = 3

Answer 5

number three is the correct answer I need to find the formula to the problem
Let f(x) = 9x - 2 and g(x) = -x + 3. Find f(g(x)). and I have no clue how does anyone ?

1. -9x - 2
2. -9x + 5
3. -9x + 25
4. -9x + 27

Answer 6

anyone ^^ ??

Answer 7

I really need help on this

Answer 8

Replace x in f(x) with g(x)
F(g(x))=9(-x+3)-2=-9x+27-2=-9x+25

Answer 9

thank you sooooo very much !!!!!!!!

Answer 10

U r welcome

Answer 11

can anyone help me with, Let f(x) = 2x + 2. Solve f-1(x) when x = 4. the correct answer is
1 I just need to find out the formula to find 1. does anyone have a solution ?

Answer 12

I really need help on this ?? ^^

Answer 13

R su about the answer?re

Answer 14

Yes the choices are
1
3
4
10

1 Is correct

Answer 15

I need the formula

Answer 16

Oh need to find the inverse of the function

Answer 17

how do I do that ?

Answer 18

This is my last problem I have no clue how to do it can you help me ?

Answer 19

X=2y+2
2y=x-2
F-1(x)=x-2/2
f-1(4)=4-2/2=2/2=1

Answer 20

Thank you very much !!!!!!

Answer 21

U r welcome:)

Answer 22
