Question
Graph the polynomial, and determine how many local maxima and minima it has.$$y=x^{3}+12 x$$
Step 1
The derivative of a function gives us the slope of the tangent line at any point, which can help us find local maxima and minima. The derivative of the function $$y=x^{3}+12 x$$ is $$y'=3x^{2}+12$$. Show more…
