Can Anyone Help me with this I believe I got the first one correct If not correct me please

Does the point (1, sqrt 7) lie on circle shown.

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
