Help me out please. This is Algebra 2 problem.

I am going to start from the top and work my way down.

If you shift f(x) down 3 units, x = 2, -1, -3, -5; f(x) = 0, 2, 4, 6

Hope this helps

If my answer is wrong let me know

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
