Question

Use graphing calculator to find the zeros and local maximum ad minimum of polynomial functions.

Answer 1

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$f(x)=x^{3}-9x+5$

using a graphing tool

see the attached figure

The local maximum is the point $(-1.73,15.39)$

The local minimum is the point $(1.73,-5.39)$

The zeros of the function are $(-3.25,0)$, $(0.58,0)$, $(2.67,0)$
