We are given y=(x^2)+3x-5. Find the derivative of y in terms of x.

From the question we have, y=x2+3x-5
The rule of differentiation, is that you take the power on the x and bring it to the front, leaving the power-1 behind. In other words if you have xn then the derivative is (n)xn-1
The question asks for the derivative of y in terms of x so we are calculating dy/dx
Using the rule of differentiation we get,dy/dx= [(2)x2-1]+[(31)x1-1]-[(50)x0-1]dy/dx=2x+3
