Question

15 POINTS!!! HELP ASAP!! What are the domain and range of the function graphed below?

A. domain: {–∞ < x < ∞}; range: {y < 2}
B. domain: {–∞ < x < ∞}; range: {y ≤ 2}
C. domain: {x ≤ 2}; range: {–∞ < y < ∞}
D. domain: {x ≥ 2}; range: {–∞ < y < ∞}

Answer 1

C. domain: {x ≤ 2}; range: {–∞ < y < ∞}

that's the right answer pramis:)

Answer 2

The answer is B because there is a y-value for every X and at 2 is a closed dot meaning there is a value of 2 for Y. Also what does It mean?
