11.4_7 Can you please help me with a step by step guide. Thank you very much! Find the average value of the function on the interval of  f(x) = 2x; [1,5]   Find all x-values in the interval for which the function is equal to its average value. (Enter your answers as a comma-separated list.) x=?

Show that the function f(x)=3(x5)2+7 is not one-to-one.

Use the Vertical Line Test to determine whether the graph represents y as a function of x.

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

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?
