Sagot :
The key features are (1) both f(x) and g(x) include domain values of [–4, ∞) and range values of (–∞, ∞), and both functions have an x-intercept in common.
How to determine the key features
The functions are given as:
f(x) = 4 - x
[tex]g(x) = -\sqrt{x - 4}[/tex]
Using a graphing calculator:
- The domain of g(x) is [4,∞)
- The range of g(x) is (-∞,0]
- The domain of f(x) is (-∞,∞)
- The range of f(x) is (-∞,∞)
- Both functions have positive values for their domains
By comparing the above highlights, the true statement between functions g(x) and f(x) is option (1)
