Give the domain and range of the relation.

y = -2

x - 7

A. domain: (-∞, 7) ∪ (7, ∞); range: (-∞, ∞)

B. domain: (-∞, -7) ∪ (7, ∞); range: (-∞, ∞)

C. domain: (-∞, 7) ∪ (7, ∞); range: (-∞, 0) ∪ (0, ∞)

D. domain: (-∞, -7) ∪ (-7, ∞); range: (-∞, 0) ∪ (0, ∞)

answer: i guess 5 units?

step-by-step explanation:

1/8 is left? add a bit more info plz

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
