So if squared by 2 means times the number by itself. would 2 squared of 60 be 120?​

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

In which form is the following function written? y = - 2(x – 3)(x + 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.
