Answer:
Option B. (-∞, 2) is the answer.
Explanation:
The given functions are f(x) = x - 3 and g(x) = -0.5x
We have to find the value of (f - g)(x)
Since (f - g)(x) = f(x) - g(x)
= (x - 3) - (-0.5x)
= x - 3 + 0.5x
= 1.5x - 3
= 1.5(x - 2)
Interval (f - g)(x) negative will be negative for x < 2.
Therefore, interval (-∞, 2) will be the interval for the negative values of the function.
Option B. will be the answer.
