I can make the sketch just having trouble understanding what is wanted.

y=0 when

y'=0 when

Relative Max(s)

Relative Min(s)

y'>0 on the interval(s)

y'<0 on the interval(s)

y is increasing on the interval(s)

y is decreasing on the interval(s)

so i got so far

y=0 when x=0

y'=0 when x=1

rel max (-1,2)

rel min (1,-2)

y'>0 on interval(s) ????

y'<0 on interval(s) ????

y is increasing on (-infinity,2)(-2,infinity)

y decreasing on (2,-2)

This means, for what range of x values is y' = 3x^2 - 3 positive, or in other words, for what range of x values is the graph of y' above the x axis

y' < 0

This means for what range of x values is y'= 3x^2 -3 negative, or in other words, for what range of x values is the graph of y' below the x axis
