Answer:
Yes, h(x) = 23 is linear. Its domain is all real numbers and its range is 23.
Step-by-step explanation:
I graphed the function h(x) = 23 on Desmos, and sure enough, it is a linear function since it is a straight line. Domain is all the possible x-values, and it looks like the line just goes on forever in both directions so the domain is all real numbers.
The range is all the possible y-values, and the only y-value available is 23. For every x-value, the y-value is 23. So, the range of the function is 23. Hopefully that's all helpful! :)
