Question

Use the definition  to find the derivative at x.
-f(x) = 13x - 12
A) 13x 
B) 1 
C) 13 
D) -13

Quizplus · Accepted Answer

The derivative of a constant term is 0, so the derivative of -12 is 0. The derivative of 13x is simply 13. Therefore, the derivative of f(x) = 13x - 12 is 13. The derivative of a linear function like f(x) = mx + b is simply the slope, which in this case is m = 13. Therefore, the correct choice is C, 13.
