Question

given the f(x)=-x^3+12x^2+60x-50
find 1st and 2nd derivatives

Answer 1

find the derivative term by term

use the algebraic formula

if y = ax^(n)

y' = an x^(n-1)

Answer 2

so first derivative of -x^3 is -3 x^(3-1) = -3x^2

Answer 3

- and for + 12x^2 it is +24 x

can you continue/

Answer 4

+24 x^2?

Answer 5

Answer 6

No the derivative of 12x^2 is 24x :-

12*2 x^(2-1) = 24x

Answer 7

so far we have
f'(x) = -3x^2 + 24x

Now you have to find the derivative of 60x and -50

Answer 8

how do u do it:/ sorry that I'm asking that

Answer 9

using the formula
