that's a function

Step-by-step explanation:

it passes the vertical line test

The second one

Step-by-step explanation:

If you draw a vertical line anywhere on the graph it never crosses more than one point

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

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
