this week in math ten we learned about domain and range. I’d never done anything with domain and range before so I was a little confused at first but after watching some videos on Khan Academy I figured it out.

domain represents the x-axis and range represents the y-axis. domain is all the x values on a graph and range is all the y values. to find the domain and range you can look at a graph or make an equation

an example of one of these equations could be 2<x<8

with that equation, you would get a vertical line starting at 2 and ending with another vertical line that ends at 8

given a function f(x), the values that f(x) can take on constitute the range of the function, while all the possible x values constitute the domain
