Answer:
1 hour ago would be 3C.
3 hours ago would be 9C.
4.5 hours ago would be 13.5
Step-by-step explanation:
÷2 = 18/27 ÷3 = 6/9 ÷3= 2/3
In this problem, it will be helpful to know the vertex form of a parabola, which is listed below:
is a constant which helps to determine whether the parabola opens up or down. If 
, then the parabola opens downward and if 
, the parabola opens upwards
is the vertex of the parabola
By looking at the graph, we can first see that the graph opens downwards, meaning that . Thus, choices C and D are not valid. Now, let's use the vertex of the parabola to complete the equation.
The vertex of this parabola is (-1, 3), as shown by the graph. When we substitute this into our formula, we get:
The answer is a, 
.
Y = 3 x = 2
if y = 1 x = ?
x = 3/2
x = 1.5
x = 5*1.5 ( y = 5 x = ?)
x = 7.5
(IF THE ANSWER IS WRONG)
may be this can be that answer
x = 2/3
x = 0.67
x = 0.67*5
x = 3.35
check the answer either first or second method is correct
