Question

Which is true about the domains and ranges of the functions f(x) = 1/8sqrt(x) and g(x) = 8sqrt(x)?

Answer 1

Answer:

They have the same domain and range

Step-by-step explanation:

they're both in the first quadrant

Answer 2

Answer:

They have the same domain and range.

Step-by-step explanation:

Since both are derived from the parent graph f(x) = √x, we know that the domain of the parent graph is [0, ∞) and the range is also [0, ∞). Since both graphs are only being modified by vertical stretch/shrink, they still have the same domain and range as the parent graph. Therefore, both graphs have the same domain and range.
