Question

If f(x) = 5x + 2 and g(x) = 6x - 3, what is f(g(x))?

Answer 1

Replace x with the value of g(x)

f(g(x))= 5(6x-3) + 2

Answer 2

Now distribute 5 in 5(6x - 3)

Answer 3

can you try it?

Answer 4

When you say f(g(x)), it means take the value of g(x) and that will equal x in f(x). To make it easier, just rewrite f(x) as 5c+2, just so it's easier to read.

So:
f(c) = 5c+2
g(x) = 6x-3
When you have f(g(x)), c = 6x-3
Therefore:
f(c) = 5(6x-3)+2

Answer 5

(30x-15)+2

Answer 6

Yes!

30x - 15 + 2

what is -15 + 2?

Answer 7

-__- lol -13

Answer 8

Yes! so final answer is? ;D

Answer 9

30x-13

Answer 10

Very Good! :)
