Question

ind the derivative of f(x) = -4x2 + 11x at x = 10.

Answer 1

i got -300 am i right?

Answer 2

one rule for the powers

\[\frac{ d }{ dx }[a*x^n] = a*(n)x^{n-1}\]

Answer 3

The derivative of f(x) , at the point (10 , f(10)) , is the slope of a tangent line of f(x) through that point.

Answer 4

wait so am i wrong?

Answer 5

what did you get for the derivative f ' (x)

Answer 6

well i got -300 as my final answer

Answer 7

can you show the calculation to get that ...

Answer 8

i honestly dont remeber, i think i used the (x+h)/h formula thing
