Answer:
First, I go by finding <em>x</em><em> </em>and <em>r</em>.
After that, put the numbers (ie. x= # and r=#) into the equations. Check it by finding L.H.S and R.H.S. (ie. left hand side and right hand side)
If you are still confused, comment down and I'll try to provide better explanation!
The given function has no undefined points nor domain constraint. Thus, the domain is: .
<h3>Domain and Range</h3>
The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. An example, there is a restriction for the domain of fractions. The variable x in the denominator should be different of zero.
While the domain is related to the values of x, the range is related to the possible values of y that the function can have.
In this question, the function has no undefined points nor domain constraint. Therefore, the domain is:
