Expert Answer

Step 1

a)   It is known that, y = 0 at x-axis.

From the graph, it is observed that the x-intercepts of the function y = f(x) are −4, −2, and 3.

That is, the function f(x) = 0 at the points x = −4, −2, and 3.

Step 2

b) Obtain the interval which the function f(x) greater than or equal to 0.

From part (a), the function...
