Question

The exponential function f(x) has a horizontal asymptote at y=3 what is the end behaviour of f(x)?

Answer 1

Answer:  C) as x → -∞, y → 3

                    as x→ ∞ , y → ∞

Step-by-step explanation:

see graph

Notice that as x approaches negative infinity (goes to the left), the y value approaches the asymptote of y = 3.

And as x approaches positive infinity (goes to the right), the y-value increases without bound so goes to infinity.
