Question

If f(x) = 2x + 3 and g(x) = 4x – 5, what is f(x) ◦ g(x)?

Answer 1

is that an open circle?

Answer 2

if so then it represents a composite; so just stuff g into the x of f

Answer 3

@amistre64, your explanations are amusing.

Answer 4

By definition,
f(x) ◦ g(x) = f(g(x))

Thus f(g(x)) = 2(4x - 5) + 3 = 8x - 10 + 3 = 8x - 7

Answer 5

@Hero, thnx, bro

Answer 6

That is how you "stuff g into the x of f".

Answer 7

@Hero what does "◦" mean?

Answer 8

Hang on, I want to make sure I'm saying it right

Answer 9

lol, thnx

Answer 10

Apparently, it means "composed with"

Answer 11

So you would read f(x) ◦ g(x) as "f(x) composed with g(x)"
