Answer:
Step-by-step explanation:
Note that the cost function is , which gives us the cost of electricity for x hours of consumption
a). The function
To find out the inverse function, we interchange the labels of x and y and solve for y, that is
when solved for y we have
So the inverse function is given by .
c) We will use the inverse function to find the amount of hours the customer can use eelectricity. It is simple obtained by evaluating the inverse function at the desired cost (i.e )
that is
that is, the custome can consume at most 1.41 hours of electricity.
