I'm not sure if i'm doing this right, it's been awhile since i've had to deal with calculus!

So it says calculate the first-order derivative with respect to x:

a. y = 3x^2

Ans: F(x) = 9X^2

b. y = x^3

Ans: F(x) 3x^2

c. y=mx + b

Ans: Not sure on this one ..

d. y = 1/x

Ans: Also not sure

e. y = 37x^4

Ans: F(x) = 148x^3

f. y = x^a/b

ANS: F(x) = a/b x^a/b - 1

Okay. maybe i'm completely wrong with some of these!

any help is greatly appreciated!
