The derivative of a quotient is:

 

a...The first by derivative of the second

b....The exponent times the base raised the exponent minus one.

c.....The one below by derivative of the one above, minus the one above by derivative of the one below, over the one below squared.

3.When calculating the Minimum of the function y = x3 + 3x2 - 2, it results:

(4 points)

a....Min = -2 for x =0

b.....Min.= 2 para x = -2

c......Min. = 3 para x = 2

4.When calculating the Maximum of y = x5 - 5x4 it results:

(4 points)

a...None

b...Max = 0 for x = 0

c....Max = -256 for x = 4

5.The derivative of 1) Y =Ln (2x)3 is:

(4 points)

a...3/x

b...4/x

c....5/x

6.1) The derivative of y = Ln(ax+b) is:

(4 points)

a...a/x

b...a/2x

c...,None
