Find the value of f(-142) for the function below.

Question

f(x) = -0.2(x + 223)

Answer 1

To find f(-142), we substitute -142 for x in the function:

f(-142) = -0.2(-142 + 223)

Now, we simplify the expression inside the parentheses:

f(-142) = -0.2(81)

Finally, we multiply -0.2 by 81:

f(-142) = -16.2

Therefore, the value of f(-142) is -16.2.
