Question

Question 4 please . Using a graphing utility (geogebra) to graph the function

Answer 1

Problem N 4

we have the function

$f\mleft(x\mright)=x^4-3x^2+2x-1$

Interval (-2,2)

using a graphing tool

Local minimum value at (1,-1)

Local maximum value at (0.37,-0.65)

Increasing function

Intervals (-1.37,0.37) U (1, infinite)

Decreasing function

Intervals (-infinite, -1.37) U (0.37,1)
