1. Use the following formulas to answer the questions below: T(M,R)=R+0.6(MR)

M(x)=220x. where RR = resting heart rate, MM = maximum heart rate, and xx = age.

Recall our discussion of heart rate and composition of functions from the end of the section. Find the training heart rate function, T(M) for a person with a resting heart rate of 62 beats per minute, then find the following. (a)Find the maximum heart rate function, M(x)for a person x year of age. M(x)=,

(b) What is the maximum heart rate for a 22year-old person? The max heart rate for a 22year-old person is ______ beats per minute.

(c)What is the training heart rate for a 22-year-old person with a resting heart rate of 62 beats per minute? The training heart rate for a 22year-old person with a resting heart rate of 62 beats per minute is______ beats per minute.

(d) What is the training heart rate for a 29year-old person with a resting heart rate of 62 beats per minute? The training heart rate for a 29year-old person with a resting heart rate of 62 beats per minute is______ beats per minute.

(e)What is the training heart rate for a 35year-old person with a resting heart rate of 62 beats per minute? The training heart rate for a 35year-old person with a resting heart rate of 62 beats per minute is _____beats per minute.

2. Let f(x)=x24x and g(x)=5x+2, find: (a) (fg)(x)= (b) (gf)(x)= (c) (fg)(0) (d) (gf)(0) =
