Which function is the inverse of f(x) = 2x 3? f-1(x) = –2x 3f-1(x) = 2x 3

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.

what is the original number? you forgot to add it.
