While exercising, a person's recommended target heart rate is a function of age. The recommended number of beats per minute, y , is given by the function y=f(x)=−0.85x+187 where x represents a person's age in years. Determine the number of recommended heart beats per minute for your age. Show each step in the process of this calculation.
