Chapter 11: Q. 320 (page 1069)

In the following exercises, evaluate the function:

a.g(h2)b.g(x+2)c.g(x)+g(2)

Function:g(x)=7-5x

Short Answer

Expert verified

The values of the function are:

a.g(h2)=7-5h2b.g(x+2)=-5x-3c.g(x)+g(2)=-4-5x

Step by step solution

01

Step 1. Given Information

The given function is g(x)=7-5x.

02

Part (a) Step 1.  Evaluating g(h2)

To evaluate g(h2), substituteh2forx.

g(h2)=7-5(h2)g(h2)=7-5h2

Therefore,g(h2)=7-5h2.

03

Part (b) Step 1.  Evaluating g(x+2)

To evaluate g(x+2),substitute x+2for x.

g(x+2)=7-5(x+2)g(x+2)=7-5x-10g(x+2)=-3-5x

Therefore,g(x+2)=-3-5x

04

Part (c) Step 1.  Evaluating g(x)+g(2).

To evaluate g(x)+g(2),first evaluate g(2).

g(2)=7-5(2)g(2)=7-10g(2)=-3

Now find, g(x)+g(2).

g(x)+g(2)=7-5x-3g(x)+g(2)=-5x-4

Therefore,g(x)+g(2)=-5x-4
