Answer:

Step-by-step explanation:
When given the following two functions,

One is asked to evaluate the functions for, (f(6)) and (g(-3)). One can do this by substituting the values (6) into the function (f) and (-3) into the function (g). These values will replace the parameter (x).

Simplify,

Now repeat this process for the guncion (g(x)) to evaluate for (g(-3))

Simplify,

Y=mx+b
Y=-0.5x+6
X is time in hours

The equation of the line for this question can be stated as,
What does y = when x is -1 or
What does x = when y is 2
So since the slope of the line is 2, we can assume that B and C must be the answers but since you want one answer we need to be more accurate.
The answer is C
Because when y = 0 x = -1 and when y = 2 x = 0
