Find The Domain And Range And Show Work class=

Sagot :

Answer: See step by step

Step-by-step explanation:

The domain  is possible x-values and the range is possible y-values. Let look at the figure, to find possible x-values. This is a parabola we are dealing with. Parabola are made from quadratic equations. In quadratic equations, you can have any x-value which why the lines extended infinitely to positive x-value and negative x- value so the domain is all real numbers or in interval notation ( -∞,∞). The range shows us that we have an finite number of y-values but it starts at a specific points as it starts at y=2 and there is no point above that so the the range is all real numbers less than or equal to 2. or in interval notation (-∞,2].
