Answer:
Below in bold.
Step-by-step explanation:
That would be 4/15 * 360   as there are 360 degrees in a circle
= 96 degrees.
 
        
             
        
        
        
You would take d times t seconds and find the answer
        
             
        
        
        
First, conceptually understand what an inverse function is, it makes solving it very intuitive.  An inverse function is simply a function which has points (y,x) for every point (x,y) of the parent function.  So you are essentially taking all points of the parent function and switching the x and y coordinates for each.  Those switched coordinates are produced by the "inverse function".
Mathematically then, finding the inverse function is a matter of solving for x and then switching the variable labels.  In this case:
y=2x+1  subtract 1 from both sides
y-1=2x  divide both sides by 2
(y-1)/2=x  now just switch the labels for the variables...
y=(x-1)/2  so
f^-1(x)=(x-1)/2  is the inverse of f(x)=2x+1
