$y = 3 {x}^{3} + 7x - 3 {x}^{2}$
Find dy/dx at x = 2

Answer 1

Hi...☺

Here is your answer...✌
=================================
GIVEN :
y = 3x³+7x-3x²

Differentiating both sides w.r.t. x
We get,

dy/dx = (3×3)x²+7-(3×2)x

= 9x²-6x+7

Now,

dy/dx (at x = 2)

= 9(2)²-6(2)+7

=9×4-12+7

= 36-5

= 31
