Answer

x-int: (-0.1, 0) (2.114, 0) y-int: (0,-1) Local Maximum: None Local Minimum: (1.416, -14.456) 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 $P(x) = 3x^4 - 4x^3 - 10x - 1$ See graph below. x-int: (-0.1, 0) (2.114, 0) y-int: (0,-1) Local Maximum: None Local Minimum: (1.416, -14.456)
