Step-by-step explanation:
In 13 - 17
Consider the factors of the constant term which sum to give the coefficient of the x- term
13
x² - x - 42 = (x - 7)(x + 6)
15
x² + x - 6 = (x + 3)(x - 2)
17
x² - 27x + 50 = (x - 25)(x - 2)
19
r² - 25 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , thus
r² - 25
= r² - 5² = (r - 5)(r + 5)
the answer is D x= x 5 because it make sense

Answer:
(−∞, ∞) and (−∞, ∞)
Step-by-step explanation:
One example (of many) might be y = 2x. The domain and range of this function are (−∞, ∞) and (−∞, ∞).
