Use the remainder theorem and synthetic division to find f(k).
k= -1; f(x) = x² - 4x +5

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.

I'm confused on this could anyone me and show me what i need to do to solve it.

Graph y = -|x| + 2. click on the graph until the correct one appears.
