Find the derivative of f(x) = -10x2 + 4x at x = 11.
Solution:
A derivative is the rate of change of a quantity y with respect to another quantity x.
A derivative is also termed the differential coefficient of y with respect to x.
Differentiation is the process of finding the derivative of a function.
The derivative of the equation f(x) is
f’(x) = df(x)/dx
f’(x) = (-20)x + 4
At x = 11
f’(x) = (-20)(11) + 4 = -220 + 4 = -216
Find the derivative of f(x) = -10x2 + 4x at x = 11.
Summary:
The derivative of f(x) = -10x2 + 4x at x = 11.is -216
