Solution Steps

Step 1: Determine the degree of the polynomial.

The degree of the polynomial is the highest power of x. In $f(x) = 3x^5 + 4x^3 - 2x + 5$, the highest power is 5.

Step 2: Determine the leading coefficient.

The leading coefficient is the coefficient of the term with the highest power of x. In the given polynomial, the leading coefficient is 3.

Step 3: Analyze the degree and leading coefficient to describe the end behavior.

Since the degree is odd (5) and the leading coefficient is positive (3), the end behavior is as follows: as x approaches negative infinity, f(x) approaches negative infinity; as x approaches positive infinity, f(x) approaches positive infinity. This corresponds to the graph falling to the left and rising to the right.
