Answer:

Step-by-step explanation:

f(x)=3x-12

f ' (x) = 3x^0 - 0

when you differentiate, you lower the power by one, and multiply the coeffiecient by the original power for 3x in this case we multiply 3 by 1 and lower the power of x to zero, so the x goes away.  and the derivative of any constant, in this case 12, is always 0

Answer:

4

Step-by-step explanation:

f(x) = 12 and f(x) = 3x

12/3 = 4 and the function for f(x) is 3(4)
