Answer 2

Answer:

  f(x)

Step-by-step explanation:

The value of y will be zero at the x-intercept. Using x=27 in the four functions, we find ...

  k(27) = ∛(-54) ≠ 0

  h(27) = 3∛0 = 0

  g(27) = 3 +∛0 = 3

  f(27) = ∛0 = 0

So, choices h(x) and f(x) match the x-intercept requirement.

__

When x=0, the function value is the y-intercept.

  h(0) = 3∛27 = 3·3 = 9

  f(0) = ∛27 = 3

The only function to match the x- and y-intercept requirements is f(x). It also matches the requirements for the domain and the slope.
