The roots of the equation below are 4 &-2, what are the coordinates of the vertex?
y =(x-4)(x+2)

Use the inverse of the function y=x^2-18x to find the unknown value [tex]y = \sqrt{bx + c \: + d} [/tex]

What is the name used to describe a graph where for some value of x, there exists 2 or more different values of y?

Gravel is being dumped from a conveyor belt at a rate of 25 ft3/min, and its coarseness is such that it forms a pile in the shape of a cone whose base diameter and height are always equal. how fast is the height of the pile increasing when the pile is 14 ft high? (round your answer to two decimal places.) ft/min
