differentiate f = sqrt(30), h = (x-2)(2x+3), y = 5e^x+3

These are very basic:


f(x)=30\displaystyle f(x) = \sqrt{30}

This is a constant. What is the derivative of a constant always equal?.

h(x)=(x2)(2x+3)\displaystyle h(x) = (x - 2)(2x+3)

Either expand and differentiate term by term or use the product rule.

y=5ex+3\displaystyle y = 5e^{x} + 3

Again, what is the derivative of 3, a constant?. The derivative of ex=ex\displaystyle e^{x}=e^{x}
