Identify the domain and range of the function graphed below. <br><br><br><br>​
Vladimir [108]

Answer:

Domain: (-∞, 4]

Range: [0, ∞)

General Formulas and Concepts:

<u>Algebra I</u>

  • Domain is the set of x-values that can be inputted into function f(x)
  • Range is the set of y-values that are outputted by function f(x)

Step-by-step explanation:

According to the graph, we see the line's x-value span from negative infinity to 4. Since 4 is closed dot, it is inclusive in the domain:

(-∞, 4] or x ≤ 4

According to the graph, we see the line's y-value span from 0 to infinity. Since 0 is closed dot, it is inclusive in the range:

[0, ∞) or y ≥ 0

What is the y-intercept of the line given by the equation y = 9/2x -4 Enter your answer as an ordered pair.
V125BC [204]

Answer:

(0, -4)

Step-by-step explanation:

I don't quite know how to explain it, but I was taught that the number in the equation that doesn't have a variable, in this case -4, is the y-intercept. The order pair is (0, -4) because a y-intercept is where the line crosses the y-axis and the y-axis is located on the 0 of the x-axis.
