f(x) = ; evaluate f(a + 1)
*
In f(a + 1), the a + 1 is taking the place of the x in f(x). As a result, simply plug the the a + 1 into the equation for f(x), exchanging each instance of x with a + 1: f(a + 1) =
*
Use the FOIL method to simplify : f(a + 1) =
*
Distribute the 2 into the a + 1: f(a + 1) =
*
Simplify by adding together the 2a and 2a and the 1, 2, and 5: f(a + 1) =
*
Your final answer is f(a + 1) =
