Hello everyone i need your help again asap! Thank you.

The function g(x) is defined as shown. x-1, -2 g(x) = 2x+3, -1 6-x, x23

Find a number such that if you add 8 and divide the result by 4 you will get the same answer as if you subtracted 3 from the original number and divided by 2

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
