Final answer:

The value of f(-5) is 49. The correct value of f(-5) is 49, which is not listed in the provided options (a) -35, (b) 35, (c) 21, or (d) -21.

Step-by-step explanation:

To find the value of f(-5), we need to substitute -5 for x in the given function f(x) = 7(2 - x).

So, f(-5) = 7(2 - (-5))

Now, simplify the expression, 2 - (-5) = 7

Therefore, the value of f(-5) is 7 multiplied by 7, which is equal to 49.

To determine the value of f(-5) for the function f(x) = 7(2 - x), you need to substitute x with -5 and then simplify the expression:

f(-5) = 7(2 - (-5))

f(-5) = 7(2 + 5)

f(-5) = 7(7)

f(-5) = 49

The correct value of f(-5) is 49, which is not listed in the provided options (a) -35, (b) 35, (c) 21, or (d) -21.
