To find the x-intercepts of the function \( A = -w^2 + 60w \), we need to set \( A \) equal to zero and solve for \( w \):
\[ -w^2 + 60w = 0 \]
Factoring out \( w \):
\[ w(-w + 60) = 0 \]
Setting each factor to zero gives:
- \( w = 0 \)
- \( -w + 60 = 0 \) which simplifies to \( w = 60 \)
Thus, the x-intercepts of the function are:
\[ (0, 0) \quad \text{and} \quad (60, 0) \]
Now, let's identify which answer choice correctly identifies the x-intercepts:
A) (0,0)
B) (60,0)
C) (60,0) and (30,900)
D) (0,0) and (60,0)
The correct answer is:
D) (0,0) and (60,0)
