If \(f(x)=a x^{2}+b x+c\) and \(r=\frac{-b+\sqrt{b^{2}-4 a c}}{2 a},\) find \(f(r)\) without doing any algebra and explain how you arrived at your result.
Describe how to find a parabola's vertex.
The radicand of the quadratic formula, \(b^{2}-4 a c,\) can be used to determine whether \(a x^{2}+b x+c=0\) has solutions that are rational, irrational, or not real numbers. Explain how this works. Is it possible to determine the kinds of answers that one will obtain to a quadratic equation without actually solving the equation? Explain.
If 4 times a number is decreased by 3 and this difference is squared, the result is \(9 .\) Find the number \((s)\)
If a parabola has two \(x\) -intercepts, explain how to find them.
