The linear function g is defined by g(x) = 4x.a. Show that g(3) and g(2) have a difference of 4.b. Show that when the input value increases from x to x +1, the output values g(x + 1) and g(x) have a difference of 4.The exponential function h is defined by h(x) = 4^x.a. Show that h(3) and h(2) have a quotient of 4.b. Show that when the input value increases from x to x + 1, the output values h(x + 1) and h(x) have a quotient of 4.
