Answer
\( g(x) = (x - 0)^2 + 8 \)
Solution
To translate the function \( f(x) = x^2 \) 8 units upward, you add 8 to the original function.
The general form for a vertical translation is:
\[
g(x) = f(x) + k
\]
where \( k \) is the number of units you translate the graph vertically.
For an 8-unit upward translation:
\[
g(x) = x^2 + 8
\]
To write this in the form \( a(x - h)^2 + k \):
- \( a = 1 \) (since the coefficient of \( x^2 \) is 1)
- \( h = 0 \) (no horizontal shift)
- \( k = 8 \) (the upward translation)
So, the function becomes:
\[
g(x) = 1(x - 0)^2 + 8
\]
**Final Answer:**
\[
g(x) = 1(x - 0)^2 + 8
\]

To translate the function \( f(x) = x^2 \) eight units up, you simply add 8 to the function. So, the new function \( g(x) \) becomes: \[ g(x) = x^2 + 8 \] Now, let's express it in the form \( a(x-h)^2 + k \). Here, \( a = 1 \), \( h = 0 \), and \( k = 8 \). Thus, the final answer is: \[ g(x) = 1(x-0)^2 + 8 \] In summary, \[ g(x) = (x-0)^2 + 8 \]
