Evaluating Symbolically
Functions can also be evaluated for inputs that are variables or expressions.
Example 1 Given f(x) = 3x2 + 2x, find f(h).
Step 1. Eliminate the input value "x" and replace it with parentheses.
f() = 3()2 + 2()
Step 2. Place the input value of h inside the parentheses.
f(h) = 3(h)2 + 2(h)
Step 3. Simplify the right side of the equation.
