8. Analyzing Graphs of Polynomial Functions
Sign In
Use the Zero Product Property to find the zeros of the polynomial function.
We want to graph the given polynomial function. h(x)=(x-3)(x^2+x+1) Let's start by finding the zeros of the function.
To draw the graph of the function, we will find some additional points and consider the end behavior. Let's use a table to find additional points.
x | (x-3)(x^2+x+1) | h(x)=(x-3)(x^2+x+1) |
---|---|---|
- 1 | ( - 1-3)(( - 1)^2+( - 1)+1) | - 4 |
0 | ( 0-3)( 0^2+ 0+1) | - 3 |
1 | ( 1-3)( 1^2+ 1+1) | - 6 |
2 | ( 2-3)( 2^2+ 2+1) | -7 |
