9514 1404 393

Answer:

  • domain: [2, 6]
  • range: [6, 18]

Step-by-step explanation:

The domain is the horizontal extent of the graph. When end points are involved, you have to be able to tell if they are included in the function definition, or not. Here, the solid dots mean both end points are included.

The graph extends horizontally from 2 to 6. You read this from the "x" scale at the bottom. As an inequality, the domain is written ...

  2 ≤ x ≤ 6

In interval notation, it is [2, 6]. Square brackets are used to indicate the end point values are included.

__

The range is the vertical extent of the graph. This one extends from y=6 to y=18. You read this from the "f(x)" scale on the left. The range can be written as ...

  6 ≤ y ≤ 18

  [6, 18]

The population of DeSoto rose an
Vanyuwa [196]

Answer:

Please check explanations

Step-by-step explanation:

Here, we want to make an interpretation

From the question, we have that initially when the count was started, there were 5,428 people; this means that the initial value of the data is 5,428

For the rate of change, we have that there is an average increase of 142 people for each of 5 years;

That means per 5 years, there is an increase of 142 people and this is what represents the rate of change

What is x² + 7x - 30​
Aleonysh [2.5K]

Are you looking for the value of x?

We can complete the square/factor:

x^2+7x-30=0

(x+10)(x-3)=0

By the zero product property rule, we have two equations, x+10=0 and x-3=0.

So the zeroes of x are -10 and 3

Hope this helped. Comment below if this didn't make sense.
