Q. Let

As x increases,

f(x) increases.
f(x) decreases.
f(x) increases if x < 0 and decreases if x > 0.

f(x) decreases if x < 0 and increases if x > 0.

Q. Let

As x approaches 2, f(x) approaches

2
3
-2
different numbers depending on whether x is approaching 2 from the right or from the left.
Q. The statement  means

f(a) = L

as x gets close to a, f(x) gets close to f(a)
as x gets close to a, f(x) gets close to L
as x gets close to a, f(a) gets close to L
