and verify your results using a graphing utility.

Short Answer

Expert verified

Required solution set is {1.5}.

Step by step solution

01

Step 1. Given information    

22x-1=4

02

Step 2. Calculations  

22x-1=422x-1=22So,2x-1=2ifau=avthenu=vx=1.5

03

Step 3. Graphing solution    

Graph y=22x-1and y =4 intersect at (1.5,4)

Hence the required solution set is {1.5}.
