Linear and Quadratic Functions
MATH 1330 Precalculus 169 Each of the quadratic functions below is written in the form f x ax bx c() 2. For each function: (a) Find the vertex ( , )hk of the parabola by using the formulas 2 b a h and 2 b a kf . (Note: When only the vertex is needed, this method can be used instead of completing the square.)

www.shsu.eduwhen solving equations involving logarithms. Even though we checked our answers graphically, extraneous solutions are easy to spot - any supposed solution which causes a negative number inside a logarithm needs to be discarded. As with the equations in Example6.3.1, much can be learned from checking all of the answers in Example6.4.1analytically.
