What are the domain and range of f(x)=-37
balandron [24]

Answer: Domain: All real numbers. Range: y=-37

Step-by-step explanation: The function of f(x)=-37 is a horizontal line that goes from negative infinity to positive infinity. The domain can be any number since there is no limit on what the x value can be. The range will always be y=-37 because no matter what x will equal, y will always be equal to -37 in the function of f(x)=-37.

Answer:

  3) y = -1

  5) x = -14

Step-by-step explanation:

The first step is to recognize that the equation describes a vertical line in problem 3 and a horizontal line in problem 5. The perpendicular to a vertical line is a horizontal line, and vice versa.

__

3. To make the desired horizontal line go through the point (-8, -1) the y-value of the line must match that of the point:

  y = -1

__

5. To make the desired vertical line go through the point (-14, 81), the x-value of the line must match that of the point:

  x = -14
