Precalculus Section 2.2 Part 2

Look at Graph A and Graph B

How many x intercepts to A and B have?

Look at Graph A and Graph B

What degree are the two graphs?

Look at Graph A and Graph B

Which graph has a negative leading coefficient?

You are finding the zeros for a polynomial and you find that x = 3 is a zero for that function. What else is true about the function?

Find the zeros of the function:

$$f\left(x\right)\ =\ x^3-x^2-2x$$  

Find the zeros of the function:

$$f\left(x\right)\ =\ 3x^4-4x^3$$  

What is the multiplicty of x = 0?

$$f\left(x\right)\ =\ 3x^4-4x^3$$  

What do you expect the zero at x = 4 to look like?

$$f\left(x\right)\ =\ \left(x+2\right)^3\left(x-1\right)$$
