Find the 1st Derivative of each of the following functions f

Find the 1st Derivative of each of the following functions:

f(x)=4x^7(8x-9)---use the produce rule

f(x)= 6x^7 + 5x^-4 -3x^2 +1

f(x)= (3x+5)/ 8x^6--use the quotient rule

f(x)=(5x^3+5)^2--use the power function rule (Chain rule)

f(x)= (8-2x)(4-2x) x

f(x)= x^2*(104-4x)

f(x)= 40x + 1500/x
