Chapter 3: Q. 56 (page 139)

Explain how the graph of f(x)=mx+b can be used to solve mx+b>0

Short Answer

Expert verified

In the graph off(x)=mx+b, all positiveyvalues of the graph of the function will representmx+b>0.

Step by step solution

01

Step 1. Given information

Given function is

mx+b>0

02

Step 2. Explanation

If the graph of f(x)=mx+b,mx+brepresent the yvalue of the function

So inequality mx+b>0 is

role="math" localid="1647292441570" mx+b>0f(x)>0y>0

So in the graph off(x)=mx+b,all positiveycoordinates of points of the graph will representmx+b>0
