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 :)
The scale factor can change how big or small a figure is, though it will still be similar. For example, a triangle with two sides measuring 3 & 3 (isosceles) are scaled in a factor of 6 (becoming larger).
3 x 6 = 18
The new triangle will have the sides measuring 18. Even though the triangles are not congruent, they are similar.

You will need to put out a picture of the cone, for me to give the correct answer.
You will have to add 190 with 95 and that will be 285 because he rides 190 miles in FOUR days and you will need to know the half of 190 to get 2 days because each day he would ride 47.5 miles each day and 47.5+47.5=95.
The Answer is 285.
