To transform the function \( f(x) = x^2 \) to \( f(x-3) + 12 \), we follow these steps:
-
Shift the function: The expression \( f(x-3) \) indicates a horizontal shift. Specifically, replacing \( x \) with \( x-3 \) shifts the graph to the right by 3 units.
-
Vertical shift: The addition of 12, as in \( +12 \), indicates a vertical shift upward by 12 units.
Therefore, the correct combination of transformations is:
Shift to the right 3 units and shift up 12 units.
