Question

If f(x) = 3x + 1 and g(x) = 2x − 4, find f[g(2)].

25

4

0

1

Answer 1

first find g(2)

Answer 2

then the value which comes substitute it

Answer 3

g(2)=2(2)-4
and f[g(2])= 3[g(2)] + 1

Answer 4

im still confused

Answer 5

g(x) is your inside function, so you plug in 2 there

Answer 6

what is the value of g(2) @isaiahw.

Answer 7

4f?

Answer 8

g(2) = 2x2-4 = 0

Answer 9

thus f(g[2]) = f(0) = 3x0 + 1 = 1

Answer 10

First get g(2) from g(x) given
then you get a value..
put that value in f(x) and calculate
