Consider the function f(x)=x^3+2x^2-3

 

A. Graph the function

B. What are the x- and y-intercepts of the graph?

We can graph it using Desmos's calculator,  here .

 

It crosses the y-axis at  (0, -3) , so the y-intercept is  -3 .

 

It crosses the x-axis at  (1, 0) , so the x-intercept is  1 .

 

Its degree is  3 , so it can't have more than  2  turning points.

So we know that there's not another x-intercept way out that we can't see.   smiley

xintercept = 1

yintercept = -3
