The solution of the inequality is 6,3 .

The graph is solution set is shown below

  PRECALCULUS:GRAPH...-NASTA ED.(FLORIDA), Chapter P, Problem 59RE , additional homework tip  1

Given:

The inequality, 2<x+47 .

Concept Used:

  • If there is the strict inequality symbol < or> , then use a parenthesis on the interval
  • If there is the inequality symbol  or , then use a bracket on the interval
  • To graph the endpoint with strict inequality < or>, use the open parenthesis or a hollow circle at that endpoint.
  • To graph the endpoint with inequality symbol  or, use the bracket or a solid circle at that endpoint.

Calculation:

In order to solve the given inequality 2<x+47 , add 4 to both sides and simplify further as shown below

  2<x+4724<x+44746<x3

Therefore, the solution of the inequality is 6<x3 or 6,3 .

The solution of the inequality is all real number that are greater than 6 and less than or equal to 3. Since the inequality sign is strict with 6 , use a hollow circle at 6 and a solid circle at the right endpoint 3as shown in below graph,
