Question

Describe the step one has to follow yo graph one variable inequalities

Answer 1

Problem:

Let's denote the age of a child by x. Then if a child can only enter the jumping castle if he/she is less than 15 years old, this means that:

`x\text{ }\leq15`

That is equivalent to the interval

`(-\infty,15\rbrack`

But the age of the child cant be negative so the correct interval would be:

`(0,15\rbrack`

0 does not belong to the interval because a child with 0 years does not exist. So the graph for the above inequality is:
