# Increasing and Decreasing Functions Worksheet (with Answer Key +  pdf)

For a given function, y = f(x), the function is known as an increasing function if the value of y increases as the value of x increases, and the function is known as a decreasing function if the value of y decreases as the value of x increases. Mathematically,
