    To find x intercepts, set y=0. To find y-intercepts, set x=0.

    To find max and min, differentiate, set to 0 and solve for x. Graph if you have a calculator.

    To check which is the max and min, use the second derivative.

    But, since this is a quadratic, you will have only one extrema. Either a max or a min, not both.

    Maybe do away with those decimals and rewrite as . Looks better.
