Answer:
Domain is A
Range is D
Step-by-step explanation:
it's all x because the line will go up and down on both directions infinitely hitting every x coordinate. The range is all y because it will also extend infinitely upwards and downwards. This is not a parabola so there i no limitation
Answer: and the answer is 2x + 7
Step-by-step explanation:
as it is a polynomial in one variable, it has only one solution.
