The derivative of the function is
.
<h3>What is Derivative?</h3>
The derivative is the instantaneous rate of change of a function with respect to one of its variables.
Given function:
y= (3x²+5x+1)
Differentiating and applying chain rule
= 3/2 * (3x²+5x+1)
d/dx (3x²+5x+1)
= 3/2 * (3x²+5x+1)
(6x+5)
= 
Hence, the value of derivative is
