The difference quotient of a function f left x right is defined to be frac f left x h right f left x right h For problems 5 9 compute the difference quotient of the given function f left x right 4x 9 Solution g left x right 6 F x ax 2 bx c To this f x a x h 2 k Where h b 2a k f h In other words calculate h b 2a then find k by calculating the whole equation for x h But Why The wonderful thing about this new form is that h and k show us the very lowest or very highest point called the vertex
1 Evaluate f x x 2 3x 4 at 2 a a h Evaluate frac f a h f a h Solution Replace the x in the function with each specified value a Because the input value is a number 2 we can use simple algebra to simplify begin align f 2 2 2 3 2 4 4 6 4 6 end align b When teaching students how to compute the difference quotient in a precalculus or calculus class we need them to evaluate the expression f x h f x h for various simple functions like linear and quadratic functions Let s say
