Question

f(x) = |x|;
shrink vertically by a factor of
1/8,
shift to the left 4 units, and shift upward 9 units

Answer 1

f(x) = | 1/8 x - 4 | + 9

Answer 2

If x is on the horizontal axis, and f(x) is on the vertical axis:
Shrink vertically by a factor of 8 --> means multiply x by 1/8.
Shift to the left 4 units --> means subtract 4 from x (the horizontal component)
Shift upward 9 units --> means add 9 to the end of the equation.
