Question

Given the functions f(x) = 10x + 25 and g(x) = x + 8, which of the following functions represents f[g(x)] correctly?

f[g(x)] = 10x + 33

f[g(x)] = 10x2 + 33

f[g(x)] = 10x + 105

f[g(x)] = 10x2 + 105

Answer 2

Are you sure those are the answer choices?

Answer 3

Yes

Answer 4

you need to replace the x in f(x) with g(x) then simplify
f(g(x)) = 10(x + 8) + 25

Answer 5

So, y=10(10+8)+25?

Answer 6

f(g(x)) = 10(x + 8) + 25
That's the answer, but you have to simplify/combine like terms.
You don't have to substitute a number

Answer 7

The answer is C. f[g(x)] = 10x + 105

Answer 8

Thank You!

Answer 9

lmao. you still don't know how to do it :/

Answer 10

May you explain it to me then?

Answer 11

f(g(x)) means to literally put g(x) inside of f(x).
