Final answer:

To calculate f(7) for the function f(x) = 4x - 10, replace x with 7 and follow the arithmetic operations to get f(7) = 18.

Step-by-step explanation:

To find f(7) for the function f(x) = 4x - 10, simply substitute x with 7:

  1. Replace x in the function with 7: f(7) = 4(7) - 10.
  2. Multiply 4 by 7 to get 28: f(7) = 28 - 10.
  3. Subtract 10 from 28 to find the value of f(7): f(7) = 18.

Therefore, the value of f(7) is 18.
