Answer:
f(x) = 6
So, lets assume that we are taking derivative with respect to x:
f(x) = (6x - 8)
f(x) =
(6 - 8)
Lets take the derivative of the sum term by term:
f(x) =
(6 - 8)
f(x) =
(6x) +
(-8)
Now we need to factor out the constant:
f(x) =
(6x) +
(-8)
f(x) = 6
x +
(-8)
Let's find the derivative of a variable with respect to itself is 1:
f(x) = 6
x +
(-8)
f(x) = 6 * 1 +
(-8)
Now we multiply the numbers:
f(x) = 6 * 1 +
(-8)
f(x) = 6 +
(-8)
Now we find that the derivative of a constant is zero, so:
f(x) = 6 +
(-8)
f(x) = 6 + 0
Now we add the numbers:
f(x) = 6 + 0
f(x) = 6
The final and correct answer is
f(x) = 6
