To get the extrema, derive the function.
You get y' = 2x^-1/3 - 2.
Set this equal to zero, and you get x=0 as the location of a critical point.
Since you are on a closed interval [-1, 1], those points can also have an extrema.
Your min is right, but the max isn't at (1,1). At x=-1, you get y=5 (y = 3(-1)^2/3 -2(-1); (-1)^2/3 = 1, not -1).
Thus, the maximum is at (-1, 5).
Answer:
The ratio of 51:9 in it's simplest form is 17:3.
Answer:
y-intercepts: (-3,0) , (-1,0) , (1,0)
Step-by-step explanation:
Answer:
Step-by-step explanation:
The reciprocal of a number is 1 / the number,
so the reciprocal of x is 
.
