Question 367941: Graph the quadratic function . State the ordered pairs representing the x-intercept(s), y-intercept (if any), and the vertex of the parabola. If the parabola has a maximum or minimum, give its coordinates.
So far I have the following:
To find the y-intercept set x=0 and solve for f(x)

y-intercept is at (0,5)
To find the x-intercept set x=0 and solve for x

and then I get stuck...is this even right to this point? How do I finish this problem and how do I graph it? Also, how do I know if the parabola has a maximum or minimum and give its coordinates?
