Find the derivative of the function f(x) = `2x^2 + 3x + 5` at x = 1

Find the derivative at x = 2 of the function f(x) = 3x .

Sajan finds the derivate of two functions f(x) = x^2 + cos x and g(x) = x^2 cos x as follows f(x) = x^2 + cos x , f'(x) = 2x - sin x, g (x) = x^2 cos x , g'(x) = 2x ( - sin x) Sajan makes a mistake in finding derivative of one of the functions. Identify that function and find out correct derivate of that function
