Answer:
- domain: -∞ < x < ∞
- range: -2 ≤ y < ∞
Step-by-step explanation:
<u>Domain</u>
The domain is the horizontal extent of the function, the set of input values for which it is defined. A parabola that opens up or down is defined for all x values, so its domain is ...

<u>Range</u>
The range is the vertical extent of the function, the set of output values it produces. The vertex of the parabola is one extreme of the range. Depending on the direction it opens, the other extreme will be +∞ or -∞. The range includes the y-value of the vertex. Here, the range is ...

A rational number is any number that can be expressed as the quotient or fraction
Answer: y=-2x-9
Step-by-step explanation:
Add 4x to both sides because the slope (-2x) needs to be on the same side as the y-intercept (-9). Then divide everything by 2 to get your answer because you want to get y by itself, since there is two of them. 2y-4x=-18 becomes y=-2x-9.
