Question

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

Answer 1

Answer:

C. $k$ is greater than zero.

Step-by-step 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.
