THE POWER RULE
 FUNCTION FORMAT: If f (x) = xn , then f '(x) = nxn-1 OPERATOR FORMAT: ddx xn = nxn-1

[1] (value 10%) If y = x4 enter numbers below expressing y'
y' = x

[2] (value 10%) If y = x enter numbers in both boxes below expressing y' in the format of the Power Rule stated above.
y' = x

[3] (value 10%) If y = 1 enter numbers in both boxes below expressing y' in the format of the Power Rule stated above.
y' = x

[4] (value 10%)
 If y = 1 x , enter numbers below expressing y'
y' = x

[5] (value 10%)
 If y = 1 x3 , enter numbers below expressing y'
y' = x

[6] (value 10%)
If y =
 x
, enter numbers below expressing y'.
y' = x

[7] (value 10%)
 If y = x3 x- 4 , that is, the product of x3 and x- 4 , enter numbers below expressing y'
y' = x

[8] (value 10%)
If y = x3
 x
, that is, the product of x3 and
 x
, enter numbers below expressing y'
y' = x

[9] (value 10%)
If y =
x3
 x
, that is, the quotient of x3 and
 x
, enter numbers below expressing y'
y' = x

[10] (value 10%) If y = x3.14 enter numbers below expressing y'
