How do you find the MIN and MAX of a function?
Set x=0 then y=0 solving for the unknown(s) in each equation. You will now be able to obtain your minimums and maximums
How do you know when the derivative of a function is equal to ZERO by looking at the graph of the function?
Looking at a graph, when the function changes direction and there is a minimum or maximum point on the graph, this is where the derivative of the function is equal to zero.
Why is anything to the power of ZERO equal to ONE?
x^3/x^2 = x^(3-2) = x^1 = x x^3/x^3 = x^(3-3) = x^0 = 1 ... ex) x/x = 1 and 2/2 = 1
