The domain is the set of all real numbers and the range is the set of all real numbers larger than -4, so the correct option is the third one.
<h3 /><h3>How to get the domain and the range?</h3>
For a function y = f(x) we define the domain as the set of the x-values (horizontal axis) and the range as the set of the y-values (vertical axis).
Here we have a parabola, in this case the domain is always the set of all real numbers, and the range is all the values above or equal to the vertex (in cases like this, where the parabola opens up).
We can see that the vertex is at y = -4
So the range is.
[-4, ∞]
So the correct option is 3.

Answer:
the answer is 5
Step-by-step explanation:
2x/5 - 9 = -7
2x/5 = -7 + 9
2x/5 = 2
2x = 2 * 5
2x = 10
x = 10/2
x = 5
Answer is c) $157.61
Gross Income - $215
Deductions- $15.16
FICA Tax- $29.33
State Tax- $215 x 0.02 (2%)
City Tax- $215 x 0.01 (1%)
Retirement Fund- $215 x 0.03 (3%)
--------------------------------------------------
Total- $57.39
Gross Income - $215 - $57.39 = $157.61
The slope is 9/11 because if you use the formula (change in y)/(change in x), you would get -18/-22 and then if it were to be simplified, it would be 9/11
