Does anyone know how to do this? I’m lost

B

Step-by-step explanation:

To find the inverse function, you switch x with y and y with x. Then, you solve for y.

                                 [switch x with y, and y with x]                        

                                 [add both sides by 4]

                                 [square root both sides]

                                   [add both sides by 1]

Now that we know the inverse function, we can actually tell that the answer is B. We know this because of the restriction that f(x) is x≤1. This makes it positive, and B the answer.

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.

where are the choices?
