Answer:
Option C. x = 1 is the answer.
Step-by-step explanation:
If g(x) = mx + c is the first function and second function is f(x) = (-m'x) + c'
Then the solution of the given equations of the lines will be a common point lying on both the lines.
Here the common point is (1, 1) (given in the graph)
It means when we put x = 1, we get the value of y = 1 in both the equations.
In other words, for the input value of x = 1 we get the output value of both the functions f(x) = g(x) = 1
Therefore, x = 1 will be the input value.
Option C. is the answer.
