Answer:
- domain: x < -2
- range: y > 1
Step-by-step explanation:
Domain and range of the inverse function are swapped: the domain of the function is the range of its inverse, and vice versa.
__
The graph shows an example of a function and its inverse with the given domain and range. The function is red; its inverse is blue.

Answer:
480 people
Step-by-step explanation:
Set up an equation where x is the number of people surveyed:
180 = (x)(0.375)
Solve for x:
180 = (x)(0.375)
480 = x
So, Annette surveyed 480 people
Answer: $70 per year.
Step-by-step explanation:
Let's say that x is the number of years that has passed and y is how much the stamp is worth.
So we know that in zero years the stamp was worth $420 because that is the time Sheri gave her brother Sam the stamp. That could bring up the coordinates (0,420) .
Now we know that in 8 years it was worth $980 and that could be the coordinates (8,980)
To find the rate of change we need to find the different between the y value and divide it by the difference in the x values.
420 - 980 = -560
0-8 = -8
-560/-8 = 70
The rate of change is 70 which means that it grew by $70 every year.
Answer:
<em><u>True.</u></em>
Step-by-step explanation:
We have to tell about the statement true or false
Two triangles that have the same side length will always be congruent
The SSS congruency rule states that if all three sides of one triangle are equal to corresponding three sides of another triangle, then the triangles are congruent.
∴ we say that when the sides are the same then the triangles are congruent.
<u><em>Hence, the statement is true.</em></u>
Because the definition of a congruent triangle is a triangle with every side of same length.
