Use the short cut rules to find the derivative of each of te following fucntions:

a) f(x) =4x+1

b) g(x)=8x^3-5x^2+3x+1

c) f(x)= 2 square root x +1/5x^5

Multiply the power of the variable by the coefficient and reduce the power of the variable by 1.

a)

b)

c) I'm not sure what you're saying the function is. But if you have a root, such as , you can rewrite it as and then use the power rule, giving you .

Thank you for your help!!
