Answer:
f

x
)
=
9
x
−
18
Explanation:
To find the inverse or
f
−
1
(
x
) of a function we solve the equation for x
So in this example, we can start by subtracting
2 from both sides: y
−
2
=
1
9
x
+
2
−
2
Next we multiply
9 to each side to isolate the variable x 9
(
y
−
2
)
=
1
x
9
⋅
9
9
y
−
18
=
x
Since the function of a line is written in terms of y we can simply switch x and y and rewrite the equation to get: y
=
9
x−
18 or f
−
1
(
x
)
=
9

Answer:
- Is a larger (more positive) than b?
- Is c larger (more positive) than d?
Step-by-step explanation:
Since a and b are less than zero, both are negative, but we don't know their order. We need to ask the order of a and b.
Since c and d are greater than zero, both are positive, but we don't know their order. We need to ask the order of c and d.
If you know a < b, then their order left to right on the number line will be a, b. Otherwise, it will be b, a.
If you know c < d, then their order left to right on the number line will be c, d. Otherwise it will be d, c.
Depending on the answers to the questions above, the order will be one of ...
- a, b, c, d
- b, a, c, d
- a, b, d, c
- b, a, d, c
As you can see, a and b will always be left of c and d.
