Question

The graph shown below expresses a radical function that can be written in

17
the form f(x) = a(x + k)!
C. What does the graph tell you about the
value of k in this function

Answer 1

C.
`k` is greater than zero.

Explanation:

We know that graph is obtained from the function of the form
`f(x) = a\cdot (x+k)^(1/n) + c`. According to the graph and if
`x + k = 0`, we find that:

`x = -k` (1)

`x < 0` (2)

By (1) and (2):

`-k < 0`

`k > 0`

Hence, correct answer is C.
