Transcript text: Use the leading-term test to match the function $f(x)=x^{5}+\frac{1}{3} x-2$ with one of the given graphs
Choose the correct graph below.
A.
B.
c.
D.
Solution
Solution Steps
Step 1: Identify the leading term
The leading term of the polynomial $f(x) = x^5 + \frac{1}{3}x - 2$ is $x^5$.
Step 2: Determine the end behavior
Since the leading term is $x^5$, the degree is 5 (odd) and the leading coefficient is 1 (positive). Therefore, the end behavior of the graph is down to the left and up to the right.
Step 3: Match the graph
The only graph that exhibits this end behavior is B.
