f(x)=4x-1; find f (-1) +11

1 answer

To find \( f(-1) + 11 \), we first need to calculate \( f(-1) \) using the function \( f(x) = 4x - 1 \).

  1. Substitute \(-1\) into the function: \[ f(-1) = 4(-1) - 1 \] \[ f(-1) = -4 - 1 = -5 \]

  2. Now, add 11 to the result: \[ f(-1) + 11 = -5 + 11 = 6 \]

Thus, \( f(-1) + 11 = 6 \).
