3. Show why, for linear functions, a vertical translation is equivalent to a horizontal
translation. For a linear function, what horizontal translation is equivalent to a vertical
translation of 3 units up?
4. Alex says that the function f(x) = (3x)represents a vertical stretch of the quadratic
parent function by a factor of 3. Marta says that it represents a horizontal compression
1
by a factor of 3. Decide whether one student is correct, both are correct, or neither is
correct.
5. For an unknown parent function f(x), write a function g(x) that is:
O
o vertically stretched by a factor of 2,
shifted up 5 units, and
o shifted right 4 units.
6. Explain how your function accomplishes these transformations.
