Question

Which of the following could be an example of a function with a range (-infinity, a] and a domain [b, infinity) where a>0 and b>0?

Answer 1

the constant under the radical gives horizontal shift, so it's associated with the domain. The constant added/subtracted gives vertical shift so it goes with the range.
→ b has to be under the radical and a outside.

Answer 2

is it c?

Answer 3

That's got a domain of all real numbers

Answer 4

right @UsukiDoll

Answer 5

?

Answer 6

well if a function isn't a fraction there is no restriction at all.

Answer 7

I think the restriction comes from the domain of the square root.

Answer 8

But there shouldn't be a description on a cube root

Answer 9

*restriction

Answer 10

I think it's got to be the square root one.
You could always pick numbers for a and b and graph the functions to see what matches

Answer 11

so a? :/

Answer 12

yeah i'd go with a

Answer 13

okay thank you :)

Answer 14

you're welcome
