4. The function H described by H(x)=2.75x+71.48 can be used to predict the height, in centimeters, of a woman whose humerus (the bone from the elbow to the shoulder) is x cm long.

Predict the height of a woman whose humerus is_____ cm long.

The predicted height of a woman whose humerus is_____ cm long is ______cm.

5. The function, p(d)= 1+ , gives the pressure, in atmospheres(atm), at a death d in the sea (d is in feet). Note that p(0)=1 atm, p(33)=2, and so on. Find the pressure at 10 feet.

The pressure at 10 feet is _____atm.

Hi,

Please find the detailed explanation of your problems attached herewith.

Given the function f described by f(x)=x+7, find each of the following.

1. f(0)= ?

For this put x =0, we will get

f(0) = 0+7 = 7

f(0) = 7

2. f (-11)=?

For this put x = -11, we will get

f(-11) = -11 + 7 = -4

f(-11) = -4

3. F(-14)=?

For this put x = -14, we will get

f(-14) = -14 + 7 = -7

f(-14) = -7

4. F(17)=?

For this put x = 17, we will get

f(17) = 17 + 7 = ...

#### Solution Summary

This step by step solution explains the concept of finding the values of a function at a given point. It also includes word problems on linear functions.
