Which phrase best describe the translation from the graph y = 2(x-15)^2+3 to the graph of y =2(x-11)^2+3?

f(x - n) - shift the graph n units right

f(x + n) - shift the graph n units left

f(x) - n - shift the graph n units down

f(x) + n - shift the graph n units up

y = 2(x - 15)² + 3

y = 2(x -11)² + 3 = 2(x - 15 + 4)² + 3

shift the graph of y = 2(x - 15)² + 3 four units left.

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

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
