Given that y = 5x^4 + 3x^3 + 2x + 5, find dy/dx

We’re being asked to differentiate the function with respect to x. To do so, we use the general formula for differentiation, which is:‘If y = kxn, dy/dx = nkx(n-1)We must also note that, which differentiation, the constants ‘vanish’. Therefore doing so, we find that:dy/dx = 20x^3 + 9x^2 + 2.
