The end behavior of a polynomial function is determined by its leading term, which is the term with the highest degree. For the polynomial given, 2x7 – 8x6 + 3x5 – 3, the leading term is 2x7.
Since the leading term 2x7 has a degree of 7 (which is odd) and a positive coefficient (2), we can deduce the end behavior of the graph:
- As x approaches positive infinity (x → ∞), the value of the polynomial will also approach positive infinity (f(x) → ∞).
- As x approaches negative infinity (x → -∞), the value of the polynomial will approach negative infinity (f(x) → -∞).
In summary, the end behavior of the graph of the polynomial function 2x7 – 8x6 + 3x5 – 3 is that it rises to the right and falls to the left.
