Answer:

x>10

Step-by-step explanation:

Think of the < and > signs as arrow marks

Whichever direction the arrows pointing, that's where you should plot.

The line graph shown goes rightwards, so use the sign that looks like it's pointing right. (>)

Finally, don't use the greater than or equal to sign because the circle isn't colored in. This means that it doesn't include 10, only numbers higher than 10.

Match the sets of points representing one-to-one functions with the sets of points representing their inverse functions.

gogolik [260]

Given a set of points representing a function, the inverse is the interchange of the set of points. i.e. given point (a, b), the inverse is point (b, a).

Thus, given
 $h = \{(1,1), (2,2), (3,3), (4,4), (5,5), (6,6)\}$ ,
the inverse is 
$h^{-1} = \{(1,\1), (2,\2), (3,\3), (4,\4), (5,\5), (6,\6)\}$

Given
 $g = \{(1,3), (2,6), (3,9), (4,12), (5,15), (6,18)\}$
the inverse is
$g^{-1} = \{(3,1), (6,2), (9,3), (12,4), (15,5), (18,6)\}$

Given
$f = \{(1,2), (2,3), (3,4), (4,5), (5,6), (6,7)\}$
the inverse is
$f^{-1} = \{(2,1), (3,2), (4,3), (5,4), (6,5), (7,6)\}$

Given
 $i = \{(1,1), (2,3), (3,5), (4,7), (5,9), (6,11)\}$
the inverse is
$i^{-1} = \{(1,1), (3,2), (5,3), (7,4), (9,5), (11,6)\}$
