Question 1039288: A solar panel manufacturer estimates that the profit y (in dollars) generated by producing x solar panels per month is given by the equation
S(x) = 8x + 0.8x^2 − 0.002x^3 − 4000.
Graph the function in the viewing rectangle [0, 400] by [−10,000, 20,000].
For what range of values of x is the company's profit greater than $15,000? (Round your values to the nearest integer. Enter your answer using interval notation.)
