f(x) = 2x^3 − 8 for f(2)

1 answer

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, \( f(2) = 8 \).
