All of the following represent the same function except . y = x - 1
{(0, 1), (2, 3), (4, 5), (7, 8)}

x y
1 0
3 2
5 4
8 7

{(0, 1), (2, 3), (4, 5), (7, 8)}

Step-by-step explanation:

For the function:  y = x - 1    (y is one less than x)

If x =1 , y= 0

if x= 3 . y= 2

If x = 5 , y= 4

If x= 8 , y= 7

So it is same as

x y

1 0

3 2

5 4

8 7

But different from {(0, 1), (2, 3), (4, 5), (7, 8)} [here x is 1 less than y]

So,  the complete statement would be : All of the following represent the same function except {(0, 1), (2, 3), (4, 5), (7, 8)} .

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
