Assume that x equals x (t )and y equals y (t ). Let y equals x squared plus 7 and StartFraction dx Over dt EndFraction =4 when x equals 5. Find StartFraction dy Over dt EndFraction when x equals 5.

72 is the answer to this problem

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
