What are the domain and range of the function f(x)=(√x-7)+9?

the domain of the function f(x) is

the range of the function f(x) is

Step-by-step explanation:

Consider the parent function

The domain og this function is the range of this function is

The function is translated function 7 units to the right and 9 units up, so

the domain of the function f(x) is

the range of the function f(x) is

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
