How do you find the domain and range of #y = 3x + 10#?

1 Answer

Answer:

Domain and Range are valid for all real numbers.

Explanation:

Let's first see that the equation #y=3x+10# describes a line:

graph{3x+10 [-32.47, 32.48, -16.24, 16.23]}

The domain refers to the list of allowable #x# values. For this equation, all #x# values are allowed, and so we can say the domain is valid for all real numbers.

The range refers to the list of all resulting #y# values. Just as all values of #x# are valid, so too are all values of #y#.
