For a chemical reaction to occur, at least one-twelfth of the solution must be hydrogen. If there are three liters of hydrogen, in interval form, how much solution is present?
A. [3,15)
B. (1/4,3]
C. [3,4)
D. [3,36]

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex

32.5 is the answer i got thats the answer
