Can someone help me with this?

What is the nth term rule of the linear sequence below? 27 , 25 , 23 , 21 , 19 , . .

Graph y ≥ -x^2 - 1. click on the graph until the correct graph appears.

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
