The sets to which the number -√3 belongs are:
D: Rational numbers.
E: Real numbers.
<h3>To which sets the number belong?</h3>
Here we have the number:
-√3
Notice that 3 is a prime number, and the square root of 3 is then an irrational number.
If it is an irrational number, it also is a real number (Remember that the real set contains all the numbers that are either rational or irrational). And because it has a negative sign, it is a negative number.
Then the correct options are:
D: Rational numbers.
E: Real numbers.
Concluding, the sets to which the number -√3 belongs are:
D: Rational numbers.
E: Real numbers.

The graph which best represents the new function is a linear function on a coordinate plane as shown in the image below.
<h3>How to determine the graph of the new function?</h3>
First of all, we would determine the slope of the linear function as follows:
Slope, m = ⅔.
Multiplying by -4, the new slope is:
Slope = ⅔ × -4
Slope = -8/3 or 2.7.
For the equation of this line, we have:
y - y₁ = m(x - x₁)
y - 0 = -8/3(x - 3)
y - 0 = -8/3x + 8
y = -8/3x + 8
Decreasing the y-value by 1, we have:
y = -8/3x + 8
y = -8/3x + 8 - 1
y = -8/3x + 7
Therefore, we would have a linear function on a coordinate plane as shown in the image attached below.
