So first, this is point slope form. The first step is to distribute.)

Then add 4 to both sides.

Then add 2x and it becomes
Given:
The number is
.
To find:
The a+bi form of given number.
Solution:
We have,

It can be written as

![[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7Bab%7D%3D%5Csqrt%7Ba%7D%5Csqrt%7Bb%7D%5D)
![[\because \sqrt{-1}=i]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7B-1%7D%3Di%5D)

Here, real part is missing. So, it can be taken as 0.

So, a = 0 and
.
Therefore, the a+bi form of given number is
.

Answer:</h2>
Four points are always coplanar if:
A. They lie in the same plane.
C. all of them are collinear.
<h2>
Step-by-step explanation:</h2>
<u>Coplanar--</u>
The points are said to be coplanar if all of them lie in the same plane.
<u>Collinear-</u>
The points are said to be collinear if all of them lie on a straight line.
Also as we know that a line always lie in one plane and so all the points that lie on that line will also lie in the same plane.
Hence, we may say that Four points will be coplanar if all of them are collinear.
Hence, the correct options are:
Option: A and Option: C
Answer:
y = 3^x is the answer as the others are quadratic or cubic functions.
Quadratic graphs are always pointing upwards or downwards, while cubic graphs have 1 end up and 1 end down.
