Find the domain and range of the graph

Hi here! Let me know if you have questions about my

Domain: x is an element of all real numbers

D = {x∈ℝ}

Range: y is an element of all real numbers, y is equal to or greater than 1

R = {y∈ℝ | y≥1}

Step-by-step explanation:

The domain is the x-values that the graph will reach.

The graph reaches past all areas left and right. There are arrows at both ends showing that the graph continues on to positive infinity and negative infinity. There is no limit on the x-values.

The range is the y-values that the graph will reach.

The graph is shaped like a "W". On both ends, there are arrows showing that the graph will keep going higher to positive infinity. It has also touched, but will not go below, y = 1.

I hope this helps! Learn about another notation, or way, to write domain and range here:
