Find the range of the graphed function
2 answers:
Answer:
.
Step-by-step explanation:
The range of the range of the function refers to the y-values for which x is defined.
Observe that there are 5 boxes from 0 to 10 on the y-axis.
This means that each box is 2 units.
From the graph the least y-value is and the highest y-value is 8.
The range is .
Answer:
Correct choice is A
Step-by-step explanation:
The range of the function are all possible values which variable y can take.
From the given diagram you can see that the variable x changes from -4 to the 9. So the domain of the function is
Also the variable y takes its values from -4 to 8. Thus, the range is

The speed of the moving walkway relative to the airport terminal exists at 1.84 m/s.
<h3>How to estimate the speed of the moving walkway relative to the airport terminal?</h3>Let x be the speed of the walkway.
(2.8 + x) = speed of child moving in direction of the walkway
(2.8 - x) = speed of child moving against the direction of the walkway
Travel time = distance/speed
Travel time of child moving in direction of walkway = 23/(2.8+x)
Total elapsed time given = 29s
23/(2.8 + x)+ 23 / (2.8-x) = 29
LCD = (2.8 + x)(2.8 - x)
simplifying the equation, we get
Speed of walkway = 1.84 m/s
The speed of the moving walkway relative to the airport terminal exists at 1.84 m/s.
