The graph of a function g is a transformation of the graph of f (x) = 18x + 20, where g(x) is 25% of f (2) Write a rule for g g(x) =

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
