Answer 1

The range deals with all y-values, so in analyzing your function, is has a closed point at \(\color{blue}{(-2,1)}\) therefore your point there is inclusive, and your range is constantly increasing from 1 and beyond due to it being an increasing function with a positive slope, so we would have \(\color{blue}R = \color{red}{[1,\infty)}\)
