Step 1:
The parent function is the function before the transformation.
Step 2:
[tex]\begin{gathered} \text{The function f(x) = x}^2\text{ was translated 4 units up to form } \\ \text{the function f(x) = x}^2\text{ + 4} \end{gathered}[/tex]
Step 3:
[tex]\text{The parent function before transformation is f(x) = x}^2[/tex]
Final answer
[tex]\text{Parent function is f(x) = x}^2[/tex]
