Domain and range of the function and it’s inverse

Mathematics

1 answer:

sineoko [7]3 years ago

8 0

Answer:

B (second table in list)

Step-by-step explanation:

The function is a quadratic with vertex and y-intercept at (0,-2). The parabola opens up meaning only y - values above -2 are a part of the function. Since range is the set of all y values, then the range is $y\geq -2$ .

The domain is not restricted and it is all real numbers.

The inverse of the function is where x and y are switched. So the range becomes the domain and vice verse.

This means the domain of the inverse is $x\geq -2$ and the range of the inverse is all real numbers.

wo competing companies are having sales on projectors. Projector #MD375 has a retail price of $1,200. The Office Spot is adverti

pshichka [43]

The amount of money that is saved by purchasing the projector at Office and beyond is $144.

<h3>How much money is saved?
</h3>

The first step is to determine the price of the projector at The Office spot.

Discounted price : (1 - 0.20) x $1200

0.80 x $1200 = $960

The second step is to determine the price of the projector at the Office and Beyond.

Discounted price : (1 - 0.15) x $960 = $816

Difference in price : 960 - 816 = $144

Please help problems below!!

kap26 [50]

Answer:

9. B 10. C 11. A 12. C

Step-by-step explanation:

Greater rate of change simply means slope! Which ever of the functions has the greatest slope (positive or negative)

a. The graph shows the line going up by 4, and across by 3, or, a slope of 4/3

b. the table is increasing by 10, so, 10/1

c. -6 = -6/1, out of all of these, we divide by the denominators and determine which number is the greatest, ignoring whether or not the value is positive or negative

a. 4/3 = 1.333333

b. 10/1 = 10

c. -6/1 = -6 (remember, ignore the sign)

In this case, B is the greatest number, therefore, it has the greatest rate of change

10.

a. -3 / 3 = -1 (ignore the negative!)

b. 2/1 = 2

c. 4/1 = 4

In this case, C, is the greatest number, meaning its rate of change is highest

11.

a. -1/3 = -0.333333 (ignore the yk what!)

b. 0.25/1 = 0.25

c. -1/5 = -0.20 (you already know)

In this case, a, is the greatest number, meaning, its rate of change is the highest

12.

a. 0/1 = 0

b. 0.5/1 = 0.5

c. 2/1 = 2

In this case, c, is the greatest number, meaning, its rate of change is the highest.

Which of the following sets of numbers could not represent the three sides of a triangle?

timama [110]

Answer:

Step-by-step explanation:

In order for the sides lengths to form a triangle, the sum of the shortest two must exceed the longest.

That will not be the case for ...

{13, 16, 30}

because 13 +16 = 29 < 30.

(13, 16, 30} could not form a triangle
