Step-by-step explanation:

Well there is no real answer to this, but, replace the numbers, -1, 0 and 1 with the x, for example,

If x is -1, then y is

y=2*-1 + 1 which is -1, so y is -1

y=-1

second, for 0, 2*0+1 is 1, so y is 1

y=1

Third, if x is 1 then y is, y=2*1+1  so y is 3

y=3

so you're 3 y's would be, -1, 1 and 3.

Cheers!

You are at a festival and notice a lady is making winter wear by knitting. She sells five hats and three scarves for a total cos
expeople1 [14]

Answer:

Cost of Hats = $15

Cost of Scarves = $8

Step-by-step explanation:

Let

Cost of Hats = x

Cost of Scarves = y

5x + 3y = 99 (1)

3x + 5y = 85 (2)

Multiply (1) by 5 and (2) by 3

25x + 15y = 495

9x + 15y = 255

Subtract

25x - 9x = 495 - 255

16x = 240

Divide both sides by 16

x = 240 / 16

= 15

x = $15

Substitute x = 15 into

5x + 3y = 99

5(15) + 3y = 99

75 + 3y = 99

3y = 99 - 75

3y = 24

y = 24/3

= 8

y = 8

Cost of Hats = $15

Cost of Scarves = $8

<h3>How to explain the domain?</h3>

It should be noted that since x cannot take negative values in the question, the square root he undefined. Hence it is an imaginary value.

Also, You can't take the square root of negative numbers. So, x values are restricted for f(x) = ✓x for real numbers and the domain is (0, infinity).

The complete question is attached.
