Determine whether these functions are invertible. find inverses of the invertible functions.
(a) f(x) = x−2.
(b) f(x) = x^{2}, where x ∈ r.
(c) f(x) = x^{2}, where x ∈ (2, 5).
(d) f(x) = x^{3}.

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

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)
