Question

Bare with me, fractions.
If f(x) = 3x and g(x) = 1/3x, which expression could be used to verify that g(x) is the inverse of f(x)?
A. 3x(x/3)
B. (1/3x)(3x)
C. 1/3(3x)
D. 1/3(1/3x)

I was thinking C but I'm not too entirely sure because the way they worded it, I don't understand it.

Answer 1

g(x)=1/f(x) It is simply: 1/number

Answer 2

It's not stating 1 over f(x). It is stating one-third x.

Answer 3

I think its C

Answer 4

let me check one more time

Answer 5

1/3 = one-third, meaning 1/3x = one-third x.

Answer 6

So it would be one-third multiplied by 3x.
