What are the period and phase shift for f(x) = tan(2x +

period: pi over two; phase shift: x = negative pi over two

period: negative pi over two; phase shift: x = pi over two

period: __; phase shift: x = negative pi over two

period: __; phase shift: x = pi over two

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.
