Front

What is function notation?

Back

Function notation is a way to represent a function using symbols. It typically uses the letter 'f' followed by an input variable in parentheses, such as f(x).

What is the process to solve f(x) = 35 for x if f(x) = 2x + 10?

Back

Set 2x + 10 = 35, then solve for x: 2x = 25, x = 12.5.
