Can sum1 the please help with where to place them?

D: x = (-∞, ∞)     R: y = (-∞, ∞)

              D: x = [0, ∞)       R: y = [2, ∞)

              D: x = (-∞, ∞)     R: y = [-3, ∞)

Step-by-step explanation:

Domain is all of the x-values

Range is all of the y-values

y = 2x - 1:  there is no restriction on x     →  x = All Real Numbers

                 there is no restriction on y         y = All Real Numbers

y = 2 + :  x is restricted by the square root    →    x ≥ 0

                    y = 2 + (0 or greater)                        →   y ≥ 2

y = x² - 4x + 3 : there is no restriction on x     →    x = All Real Numbers

quadratic equation has a minimum at vertex   →  y ≥ -3

what i would say the best answer is a. 40.5
