1. Solve the following equation algebraically. Explain your process.

0 =18x4+87x3+3x2108x

2.

a) Describe the transformations on the cubic function below. Explain your thinking process. f(x)=7[_1(x5)]345

b) The point (-9, -2446) is on the transformed function f(x)=7[_1(x5)]345 use the 2

transformation statement the find the original point on the parent function. Justify your answer.

3. Determine the values of m and n for f(x)=mx3+20x2+nx35 given that (x+ 1) gives a remainder of zero, and when divided by (x 2) the remainder is 45.
