Identify the function's x- and y-intercepts.

• x-int (3,0) and y-int (0,1)

• x-int (0,3) and y-int (1,0)

• x-int (1,3) and y-int (3,1)

• x-int (3,0) and y-int none

Find the y-intercept(s) of the graph shown.

How do you find the y-intercepts of quadratic functions?

• Set y=0 and solve for x

• Set x=0 and solve for y

• Count the number of x-intercepts

• Use the Pythagorean theorem

Does the graph have a maximum or minimum?
