How does the period of f(x)= cos⁡(2x) relate to the period of the parent function cos⁡ x?

Both have the same period which is 2π

Step-by-step explanation:

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.

the answer is 3/2 and for decimal: 1.5

hope i
