Final answer:
For the given function f(x) = 8 - 4x, the values are f(-8) = 40, f(c) = 8 - 4c (indeterminate without a specific value for c), f(9) = -28, and f(-8) is confirmed again as 40.
Step-by-step explanation:
For the function f(x) = 8 - 4x, we can find the indicated values by substituting the given values for x into the function.
- f(-8) = 8 - 4(-8) = 8 + 32 = 40.
- f(c) = 8 - 4c. This expression cannot be simplified further without a specific value for c.
- f(9) = 8 - 4(9) = 8 - 36 = -28.
- Since we have already calculated f(-8) and found it to be 40, f(-8) = 40
Confirming f(-8) as 40, substituting the different values into the function enables the derivation of the respective function outputs for the provided values of x.
