Good evening ,
Answer:
The graph is a line
Step-by-step explanation:
Look at the photo below for the details.
:)
1. The graph is a parabola.
2. The parabola opens up, because there's no negative number in front of
.
3. The vertext is (5,-1), because of the vertex form.
This means that that -1 will be the least y-value used on the graph and the garph will open up from there.
The range is (-1, infinity) or { y | y > -1 }.
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:
30
Step-by-step explanation:
5*2*3 - 2*0 = 30 - 0 = 30
The domain and range of the function is D) Domain: (-∞, ∞); Range: (-∞, ∞)
<h3>How to illustrate the information?</h3>
The domain is the input values, or the x values. We can put in any x values for this function.
Domain : (-∞, ∞)
The range is the output values or the y values. We can get any output values for this function
Range: (-∞, ∞)
