Answer 1

To find \( f(-4) \) for the function \( f(x) = \left( \frac{x}{8} \right)^2 \), we will substitute \( -4 \) into the function.

1. Substitute \( -4 \) for \( x \): \[ f(-4) = \left( \frac{-4}{8} \right)^2 \]

2. Simplify the fraction: \[ \frac{-4}{8} = -0.5 \]

3. Now square the result: \[ f(-4) = (-0.5)^2 = 0.25 \]

Thus, we have: \[ f(-4) = 0.25 \]
