Question

find (f)(g) if f(x) = 3x and g(x) = x + 1

Answer 1

(3x)(x + 1)
\[3x^2+3x\]

Answer 2

\(\bf f(x) = 3x \qquad g(x) = x + 1\qquad (f)(g) \implies (3x)(x + 1)\)

Answer 3

That's if you meant f(x) times g(x)

Answer 4

the options are
3x + 3

3x + 1

4x + 1

3x2 + 1

Answer 5

oh, then your question must have been f of g, which is f(g(x))
Which is:
3(x+1) = 3x + 3

Answer 6

so its... 3x+1?

Answer 7

"3(x+1) = 3x + 3"

So how did you get 3x+1?

Answer 8

its the closest lol, im just guessing. i dont understand this

Answer 9

It is 3x + 3. That's answer choice #1
