Could someone help me on how to do this Balanced model project? I don't quite understand on how to complete it.

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.

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

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
