How do you compute the intercepts of a quadratic function?
---To find the x-intercept, set y=0 and solve for x.
---To find the y-intercept, set x=0 and solve for y.

What is the number of x- and y-intercepts that quadratic functions may have?
---A quadratic can have 0,1,or 2 x-intercepts (as seen below).
