20. Find a quadratic function to model the values in the table.

A. y = -2x^2 - 3x + 3

B. y = 3x^2 + 3x - 3

C. y = -3x^2 - 3x - 3

D. y = 2x^2 + 3x + 2

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.

Given the quadratic function f(x)=3x^2-24x+49 a. use “completing the squares” to convert the quadratic function into vertex form b. state the vertex c. find the x and y intercepts d. graph the function

Which equation can be simplified to find the inverse of y = 2x2^2
