Question 138578
The y-intercept is the point where the curve crosses the y-axis, all of the x-coordinates of points on the y-axis are 0, so just evaluate f(0) (substitute 0 for x in your function and do the arithmetic)  The y-intercept will be the ordered pair (0,b) where b is the result of your evaluation of f(0).


The x-intercepts are the points where the curve intersects the x-axis.  These are the values of x that make the value of the function be zero.  So just set the function equal to zero and solve the quadratic.  The x-intercepts will be ordered pairs of the form (a,0) where a is a root of the quadratic equation.  Hint: this quadratic is a perfect square so you will only have one intercept.
