To find \( f(2) \) for the function \( f(x) = 2x^3 - 8 \), we can substitute \( x = 2 \) into the function:
\[ f(2) = 2(2)^3 - 8 \]
Calculating \( (2)^3 \):
\[ (2)^3 = 8 \]
Now substitute this back into the equation:
\[ f(2) = 2 \times 8 - 8 \]
\[ f(2) = 16 - 8 \]
\[ f(2) = 8 \]
Thus, \( f(2) = 8 \).
