Question

Given the function f( x ) = 4x + 1 evaluate and simplify the expressions below. See special instructions on how to enter your answers.

f (a)=____

f (a+h)=___

f(a+h). - f(a)/h =______

Simplify answers as much as possible. Expressions such as 4(x+2) and (x+5)^2 should be expanded.

Answer 1

f(a) = 4a + 1

f(a + h) = 4(a + h) + 1 = 4a + 4h + 1

The rest is on you.
