What is the range of the relation y = 3×2 4x if the domain is the set (1,0, 1)?Answer (1 of 3) To find the DOMAIN you just think "what numbers can x be?" To find the RANGE you just think "what numbers can y be?" That's all there is to it! f(x) = (x 1)^2 4 This is a parabola which opens downwards ( because the coefficient of x is negative) This is the vertex form of a parabola f(x) = a(x b)^2 c where the vertex is at (b, c) So in this caseThe vertex is at (1, 4) The domain is All Real Numbers and the Range is (∞, 4 (or y ≤ 4) 3 2 Quadratic Functions Mathematics Libretexts Y=x^2-4x 1 domain and range
