What does the notation lim x→-∞ P(x) represent for a polynomial function P(x)?

• The behavior of the function as x approaches positive infinity.

• The behavior of the function as x approaches negative infinity.

• The y-intercept of the function.

• The roots of the function.

If the limit of a polynomial function P(x) as x approaches positive infinity is positive infinity, what does this indicate about the graph's end behavior on the right side?

• The graph goes down.

• The graph goes up.

• The graph approaches a constant value.

• The graph oscillates.

What is the end behavior of the function f(x) shown in the graph?

• As x approaches negative infinity, f(x) approaches positive infinity; as x approaches positive infinity, f(x) approaches positive infinity.

• As x approaches negative infinity, f(x) approaches negative infinity; as x approaches positive infinity, f(x) approaches negative infinity.

• As x approaches negative infinity, f(x) approaches positive infinity; as x approaches positive infinity, f(x) approaches negative infinity.

• As x approaches negative infinity, f(x) approaches negative infinity; as x approaches positive infinity, f(x) approaches positive infinity.
