2. 
Domain:
, because any value of
is allowed and gives a number
.
Range:
, because
for any positive real
.
y-intercept: This is a point of the form
. So plug in
; we get
. So the intercept is (0, 2), or just 2. (Interestingly, you didn't get marked wrong for that...)
Asymptote: This can be deduced from the range; the asymptote is the line
.
Increasing interval: Going from left to right, there is no interval on which
is increasing, since 1/4 is between 0 and 1.
Decreasing interval: Same as the domain;
is decreasing over the entire real line.
End behavior: The range tells you
, and you know
is decreasing over its entire domain. This means that
as
, and
and
.
3. 
Domain: Same as (2),
.
Range: We can rewrite
.
for all
, so
for all
. Then the range is
.
y-intercept: We have
, so the intercept is (0, -6) (or just -6).
Asymptote: 
Increasing interval: Not increasing anywhere
Decreasing interval: 
End behavior: Similar to (2), but this time
as
and
as
.
Answer:
7*5 + -29
Step-by-step explanation:
She makes 7 payments of 5 to the store
7*5
Then she gets 29 dollars back so that would be negative
+ -29
7*5 + -29
35 -29
She has paid 6 dollars to the store
Ok so assuming that the 'x' means multiply and not 'x' as in placeolder we do
PEMDAS
parenthaseees
exponents
multipilcation or division
additon or subtraction
parethasees simplify first
(8+7)=15
(9-3)=6
now we have
2x(15)-6/2x(6)
multiply
2x15=30
6/2x6=36/2=18
now we have
30-18
12
answer is 12
The slope is always change in y value over change in x value so if you pick any 2 points on the line you’ll see that the slope is 30/40 and that simplified is 3/4 so the slop is 3/4
