Given y = 2x^2 + 3x + 2 find dy/dx

To get dy/dx from a formula y in terms of x we must differentiate y with respect to x. Generic formula for term differentiation: d/dx(ax^b) = bax^b-1 = times the coefficient by the power and minus the power by one Applying to each term in the formula gives us dy/dx = 4x + 3
