I’m not sure how to solve this...can someone explain domain and range and parabolas in general? I need an overview, I forgot how to solve this.

Answers:

Domain = All Real Numbers

Range = y≥0

X-Intercept = 0

Y-Intercept = 0

Explanation:

The domain of a parabola is how far does the parabola go on the x-axis. In the first parabola, it has infinite x-values, therefore having “all real numbers”. The range of a parabola is like the domain, but with the y-axis. It shows how high or low does a parabola go. Since the first parabola’s lowest point is at y=0 and goes up, the range is all inputs above y≥0.
