5. What transformations have taken place for the following

a). x^3+2x+4 to 3x^3+6x+12 : Everything has been multiplied by 3, which is a stretch in the y-direction sf 3

b). x^2+x+4 to 2x^2+2x+4 : Everything has been doubled except the +4 , which is a stretch in the x-direction factor 1/2

c). 2x^3 to 2(x-1)^3 : This has been moved one to the right, so it has been translated by (1)(0)

d). 2x^2-6x+1 to 2x^2-6x-11 : Everything is the same except the +1 has been moved down 12 to get -11, so it has been translated by (0)(-12)

e). (x-1)(x-4) to (x-2)(x-3) : Expanding these we get x^2-5x+4 and x^2-5x+6 , so we can see it has been moved up 2, so it has been translated by (0)(2)
