Answer: A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.
Step-by-step explanation:
<span>Answer:
(x + 4)/(x^2 - 3x - 10) * (x - 3)/(x^2 + x - 12)
= (x - 3)(x + 4) / (x + 2)(x - 5)(x + 4)(x - 3)
= 1/(x + 2)(x - 5)</span>
