Answer

x-int: (-.532, 0) (0.653, 0) (2.879, 0) y-int: (0,-2) Local Maximum: (2, 6) Local Minimum: (0, -2) See graph below.

Work Step by Step

The question asks for the graph, the x and y-intercepts, and the coordinates of all local extrema. This graph will be done in Desmos; the gray dots on the graph represent the x-intercepts, y-intercepts, and all local extrema Given $P(x) = -2x^3 + 6x^2 - 2$ See graph below. x-int: (-.532, 0) (0.653, 0) (2.879, 0) y-int: (0,-2) Local Maximum: (2, 6) Local Minimum: (0, -2)
