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.
