3.3: Domain and Range
1+y \ge 0 1+y ≥ 0. which means that y \ge -1 y ≥ −1. If we use interval notation, we can write Range (f) = [-1, +\infty) Range(f) = [−1,+∞) . In this example, we could have solved it using the fact that f (x) = x^2 - 4x + 3 f (x) = x2 −4x+3 is a

How to get the domain and range from the graph of a function
Solution: This is a quadratic graph, so it stretches horizontally from negative infinity to positive infinity. That means that the domain is all real numbers of x. We also see that the graph extends vertically from 5 to positive infinity.
