Question

If y = x³ - 2x², then dy dx at x = 2 is​

Answer 1

Answer:

mark me brainlist

Explanation:

Slope of given line = 3

and

dy/dx = 3x^2-4x-1

so,

3 = 3x^2-4x-1

3x^2-4x-4 = 0

so,

X = 2 & -2/3

Answer 2

Explanation:

$= > 3 {x}^{2} - 4x = > 3(4) - 4(2) \\ = > 12 - 8 = > 4$

4 is the answer of the question
