h-1(x) . To find the inverse we will replace x by y and f(x) with x in f(x) = 2x+5 and for finding h-1(x) we will replace x with y and h(x) with x in h(x) = (7-3x)/3 and solve for y. Here are the functions: x = 2y + 5 Here we replace f(x) with y: 2y = x - 5 Here we switch the y and the x: y = ((x-5))/2 Now we solve for y:
