Answer:
The best approximation for the input value when f(x) = g(x) is x = 1.5.
Explanation:
The function f(x) passes through the points (-3,1) and (0,1) and the point (1.5,1).
Therefore, the line has equation y = 1.
Now, the function g(x) passes through the points (0,-1), (1.5,1) and (3,3) points.
Therefore, the function g(x) crosses the line y = 1 at the point (1.5,1).
Hence, the best approximation for the input value when f(x) = g(x) is x = 1.5. (Answer)
