Answer:
Because -3-/8 itself is an irrational number. No matter the operation it wil always be irrational
Step-by-step explanation:
Here, Take any two coordinates: (0, 1) & (4, -2)
Slope, m = y2 - y1 / x2 - x1
m = 1 - (-2) / 0 - 4
m = 3/-4
m = -3/4
In short, Your Answer would be Option D
Hope this helps!
The domain of the function is the union of all of the "if" parts of the function definition:
... (-∞, -1) ∪ [-1, 1] ∪ (1, ∞) = (-∞, ∞)
