Write the function below in the form y = f(u) and u = g(x), then find as a function of x. dx
y=cot ( secx)

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

i believe a. 12x≥120 is the answer

i would think "anyone would want the best for their child" is correct
