The graph of the function $f (x) = x^{3} + 5 x^{2} + 2 x - 8$ is shown below. What is the solution to the equation $x^{3} + 5 x^{2} + 2 x - 8 = 0$ ?

x = -4, -2, and 1

x = -4, 2, and 1

x = -4, -1, and 4

x = -2, 1, and 4

Suppose the only transformation applied to the graph of the function $f (x) = 6 x^{4}$ were a reflection across the x-axis. The result would be the graph of which of these function?

$f (x) = - 6 x^{4} - 6$

$f (x) = - 6 x^{4}$

$f (x) = 6 x^{4}$

$f (x) = 6 x^{4} + 6$
