You go shopping and want to buy a few shirts and a pair of jeans. The pair of jeans cost $35 while each shirt has a sale price of $10. You determine the function, which represents the total cost of the clothing is f left parenthesis x right parenthesis equals 10 x plus 35, where x is the amount of shirts you buy. Doing some algebra, you determine the inverse function to be f to the power of negative 1 end exponent open parentheses x close parentheses equals fraction numerator x minus 35 over denominator 10 end fraction.
