The function f(x) = 2x/x+5 is one to onea. Find its inverse and check your answerb. Find the domain and the range of f and f^-1

During a nine-hour snowstorm, it snows at a rate of 1 inch per hour for the first 2 hours, at a rate of 2 inches per hour for the next 6 hours, and at a rate of 0.5 inch per hour for the final hour. Write and graph a piecewise-defined function that gives the depth of the snow during the snowstorm. How many inches of snow accumulated from the storm?

Find f(1) and f(2). f(x)=x+7

Can a function be its own inverse? Explain.

Graph: f(x)=x .
