For the function \( f(x) = 215x + 71 - 1 \), evaluate \( f(-4) \).

Provide your answer below:

\( f(-4) = \)

Answer :

Final answer:

The value of f(-4) is -791.

Explanation:

To evaluate the function f(x) = 215x + 71 – 1 at x = -4, we substitute -4 for x in the function:

f(-4) = 215(-4) + 71 – 1

Now, we simplify the expression:

f(-4) = -860 + 71 – 1

f(-4) = -790 – 1

f(-4) = -791

Therefore, f(-4) = -791.
