Answer: odd and positive
How to find number of degrees: Count the number of turns and add one. In this case you have 4 curves, so 4+1= 5.
How to find leading coefficient: look at the RIGHT side of the graph, the arrow is going towards positive infinity, thus making the leading coefficient positive.
Since n>2 n
n can be 3 for example
so a3=t
and from the sequence we know a3 = 15
because it is the product of a1(3) and a2( 5)
so t = 15
