If s(x)=x-7 and t(x)=4x^2-x+3 which expression is equivalent to (t•s)(x)?

4(x-7)^2-x-7+3
4(x-7)^2-(x-7)+3
(4x^2-x+3)-7
(4x^2-x+3)(x-7)

The equation represents the function f, and the graph represents the function g. f(x)=3(5/2)^x determine the relationship between the growth factors of f and g. a. the growth factor of g is twice the growth factor of f. b. the growth factor of f is twice the growth factor of g. c. the growth factor of f is 2.5 times the growth factor of g. d. the growth factor of f is the same as the growth factor of g.
