The range of the quadratic function is [-1, ∞) after plotting the function on the coordinate plane.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The function is:
f(x) = (x - 4)(x - 2)
The above function is a quadratic function.
The above function can be written as:
f(x) = x² - 6x + 8
From the graph,
The minimum value of graph at x = 3 is y = -1
The range of the function is [-1, ∞)
Thus, the range of the quadratic function is [-1, ∞) after plotting the function on the coordinate plane.

Let s be standard and h be high-quality versions of the song.
To figure this out, let's make a system of equations:
2.5s + 4.5h = 5740
h = 4s
First substitute the second equation into the first for h.
2.5s + 18s =5740
Then combine like terms.
20.5s = 5740
Lastly, divide each side by 20.5 to get the number of standard downloads:
s = 280
Hope this helps!
80% of 22 can be written in the following ways:
1) 80% of 22 = 17.6
2) 0.8 x 22 = 17.6
The percentage is converted into decimal form.
3) 80/100 x 22 = 17.6
The percentage is converted into fraction form.
80/100 can be simplified to 4/5, and the point 3 can also be written as:
4) 4/5 x 22 = 17.6
Thus, following options have the same value as 80% of 22.
Option <span>A. 80/100 ⋅ 22
Option </span><span>D. 0.8 ⋅ 22
Option E. 4/5 ⋅ 22</span>
Answer:
4 + 2i
Step-by-step explanation:
First distribute;
7 - 3 - 4i + 6i
= 4 + 2i
