To solve for \( f \), given the equation \( f^2 = 49 \), we can take the square root of both sides.

Taking the square root gives us:

\[ f = \sqrt{49} \quad \text{or} \quad f = -\sqrt{49} \]

Since \( \sqrt{49} = 7 \), we have:

\[ f = 7 \quad \text{or} \quad f = -7 \]

Therefore, the solutions for \( f \) are:

\[ f = 7 \quad \text{or} \quad f = -7 \]
