Question

Need help!!
For the function f(x)= 6x^2-4, estimate the instantaneous rate of change for the given value x
a) x=-2

Answer 1

diffrentiate it and put x=-2

Answer 2

where we have to put -2

Answer 3

first diffrentiate and tell what u got

Answer 4

like how

Answer 5

it will come 12x

Answer 6

then put x=-2 in 12x

Answer 7

how you get 12x

Answer 8

u know how to diffrentiate

Answer 9

I know but I forget

Answer 10

If u shown me then I will give a medal lol

Answer 11

diffrentiation of f(x)^n=n(f(x))^n-1

Answer 12

so here 6x^2 on diffrentiation becomes 2.6x and 4 is constant so its diffrentiation is 0
