Final answer:
To find the values of the function f(x) = 4 - 8x for f(-8), f(0), and f(3), substitute the respective x values into the function. The results are f(-8) = 68, f(0) = 4, and f(3) = -20.
Step-by-step explanation:
The question involves evaluating a linear function for given values. The function is f(x) = 4 - 8x, and we need to find f(-8), f(0), and f(3). Here is the step-by-step calculation for each:
f(-8): Substitute -8 for x in the function, so
f(-8) = 4 - 8(-8)
= 4 + 64
= 68.
f(0): Substitute 0 for x in the function, so
f(0) = 4 - 8(0)
= 4.
f(3): Substitute 3 for x in the function, so
f(3) = 4 - 8(3)
= 4 - 24
= -20.
The values found are
f(-8) = 68,
f(0) = 4, and
f(3) = -20.
