The graph of the function is attached below. Graph (b) is correct.

Further explanation:

Given:

The function is

Explanation:

The given function is .

The graph of the function represents downward parabola as the function has negative sign.

Solve the function to obtain the zeroes.

The zeroes of the function are and .

In graph 2 the zeros are and .
