The correct Answer is:
To find the zeros of the function \( f(x) = 25 - (x + 2)^2 \), we need to set the function equal to zero and solve for \( x \). ### Step-by-Step Solution: 1. **Set the function equal to zero**: \[ f(x) = 0 \implies 25 - (x + 2)^2 = 0 \] 2. **Rearrange the equation**: \[ (x + 2)^2 = 25 \] 3. **Take the square root of both sides**: \[ x + 2 = \pm \sqrt{25} \] Since \( \sqrt{25} = 5 \), we have: \[ x + 2 = 5 \quad \text{or} \quad x + 2 = -5 \] 4. **Solve for \( x \)**: - For the first equation: \[ x + 2 = 5 \implies x = 5 - 2 = 3 \] - For the second equation: \[ x + 2 = -5 \implies x = -5 - 2 = -7 \] 5. **Conclusion**: The zeros of the function are \( x = 3 \) and \( x = -7 \). ### Final Answer: The zeros of the function \( f(x) = 25 - (x + 2)^2 \) are \( x = 3 \) and \( x = -7 \).
