7 Find the following Difference Quotient for f () = and simplify the answer completely. a +4 f (5 + h) - f(5) hGiven the function f(a) = 2 + 1x, evaluate and simplify the difference quotient below. See special instructions on how to enter your answer. f(ath) - f(a) h Instructions: Simplify answers as much as possible. Expressions such as 4(a + 2) and (a + 5) should be expanded. Also collect like terms, so 3x + x should be written as 4x
