Given the graph:
Let's determine if the graph represents a polynomial function.
A polynomial function can be said to be a function which has non negative exponents and has only positive integers as the exponents.
It can be categorized as a quadratic function, cubic function, quartic function, etc.
Yes, the given graph represents a polynomial function and it is a quartic function.
The graph has 3 turning points.
A quartic graph has 3 turning points
The type of polynomial function shown in the graph is a quartic function.
ANSWER:
Yes, it is a quartic polynomial function.
