PLZZZZ HELPPP FOR BRAINLIEST! COMPARING EXPONENTIAL FUNCTIONS WHICH STATEMENT CORRECTLY COMPARES FUNCTIONS F AND G

  B.  Left limits are the same; right limits are different.

Step-by-step explanation:

When we talk about "end behavior," we are generally concerned with the limiting behavior of the function for x-values of large magnitude. Decreasing exponential functions all have the same end behavior: they approach infinity on the left (for large negative values of x), and they approach a horizontal asymptote on the right (for large positive values of x).

If we are to write the end behavior in terms of specific limiting values, we would have to say that ...

  as x → -∞, f(x) → ∞

  as x → -∞, g(x) → ∞ . . . . . . the same end behavior as  f(x)

__

and ...

  as x → ∞, f(x) → -4

  as x → ∞, g(x) → (some constant between 0 and 5) . . . . . different from f(x)

__

So, in terms of these limiting values, the left-end behavior is the same; the right-end behavior is different for the two functions, matching choice B.

all real numbers greater than or equal to 0

Step-by-step explanation:

The domain of the function is whatever the input (in this case, x) can be. As you cannot take the square root of a negative number, x cannot be negative. Because you can take the square root of 0 (which is 0), x can be anything postive or 0, meaning anything greather than or equal to 0. The domain is all real numbers greater than or equal to 0.
