Answer:
Explanation:
The graph of this is a parabola which opens upwards and x can be any value from -infinity to infinity ( the domain).
Unless you mean 7 / (2x^2 - 16x + 30), then
7 / (2x^2 - 16x + 30) =7 / 2 ((x - 3)(x - 5)
- this has asymptotes ate x = 3 and x = 5 so
the domain will be -∝ to ∝ except for x = 3 and x = 5
which can be written as
(-∝, 3) U (3, 5) U (5, ∝)
