We have a function,
and we are asked to find its inverse function.
An inverse function essentially gets you the original value that was dropped into a function.
For example,
If I put 5 into 
I will get 24. Now If I take 24 and put it into the inverse function I have to get number 5 back.
The way to determine the inverse function swap the x and the , then solve for ,
Of course the notation demands that the obtained function be called,
Hope this helps :)
Answer:
<em>she will be back at 7:30pm</em>
Step-by-step explanation:
From the question we are given
Time that Shasta leaves for her best friend place = 5:00pm
If she is to come back after 2 and a half hour, hence we will have to add 2hr 3ominutes to the time she left to know the time she will be back as shown:
She will be back at 5:00 + 2hr 30min = 7:30pm
<em>Hence she will be back at 7:30pm</em>
<span>A coefficient in the expression is a numerical or constant quantity that is placed before and multiplying the variable in an algebraic expression, for example in expression 5x + 4; 5 is the coefficient.
So in the given expression 3x/13 + 4. 3 / 13 is the coefficient of x, as 3 / 13 is multiplying with x.</span>
I believe the answer is B) 9
