Try it now. Enter the interval equivalent to 2

<

x

≤

5

or

x

>

7

We have that

The  interval equivalent to each range is given below

From the Question we are told that

2  <  x  ≤  5   or   x  >7

Generally the interval equivalent is given as follow from the number line

(...-1,0,1...)

For 2  <  x  ≤  5  

Here  this means x is less than 2 and less than or equal to 5

Therefore

A range of numbers

For  x  >7

Here x is greater than 7  i.e

in conclusion

The  interval equivalent to each range is given below
