Directions for #23-30: Select all the transformations that are happening to the function.
1

f(x) = x; g(x) = -x+2

1

f(x) = x; g(x) = 1/3x

1

f(x) = x; g(x) = -1/5x - 6

1

f(x) = x; g(x) = 4x + 5

1

f(x) = x; g(x) = -10x

1

f(x) = x; g(x) = 5/7x - 3

1

f(x) = x; g(x) = 2x +4

1

f(x) = x; g(x) = -3/2x + 1
