Can y’all me answer these questions

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 .

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
