Question

find the derivative for y=x^4+3x^2+2x+1​

Answer 1

Step-by-step explanation:

here is ur ans that I had give plz follow me

Answer 2

To differentiate :

y = x⁴ + 3x² + 2x + 1

Differentiate both side w.r.t x

=> dy/dx = d/ dx ( x⁴ +3x² + 2x + 1 )

=> dy/dx = 4x^(4-1) + 3 • 2 x^(2-1) + 2 x^(1-1) + 0

=> dy/dx = 4x³ + 6x + 2 .

Formula used :

• d/dx ( x^ n ) = nx^ (n-1)

• d/dx ( constant ) = 0 .
