Answer 1

Answer: Option C

`a> 0`

Explanation:

The graph shows a radical function of the form
`f(x)=a(x+k)^{(1)/(n)}+c`

Where n is a positive number.

For this type of function, if the coefficient
`a> 0` then then when x tends to
`\infty` f(x) tends to
`\infty` and when x tends to
`-\infty` then f(x) tends to
`-\infty`.

Notice in the graph that as x increases then f(x) also increases and as x decreases f(x) also decreases.

This indicates that the coefficient
`a> 0`
