Inverse of One-to-One Functions

Please give an explanation and solution. COMPLETE.

PART 1.

Find the inverse of the function, if it exists. Justify if it does not exist. 1. p(x) = 3x + 8 2. f (x) = x2 + 2x -1 3. g(x) = 2x +7 4. f(x) = x3-5 5. h(x) = *+2 2x-3Given the function, f(x) = 4-5x, do the following: 1. Find its inverse. 2. Sketch the graph of the functions by assigning values from the ' domain of the function. 3. Prove that they are inverses of each other
