This is an "W" shaped graph.
In general, this is a 4th degree polynomial.
Since it is an "upside down W" curve, the leading coefficient is negative.
The number of x-axis cutting points gives us the number of real zeros.
Looking at the graph, we can say that there are "3" real zeroes of this curve.
Also, looking at the graph, we can see that there is "1" relative minimum (dip) in the curve.
Answer:
the degree of f(x) is "4" and the leading coefficient is "negative". There are "3" real zeroes and "1" relative minimum values.
