(b)
A polynomial has the form
± 
+ ....
the only expression fitting this description is : x² + 2x + 7
A sequence<span> is a set of numbers.
</span>If the difference between two consecutive terms is constant, then the sequence is called arithmetic and th<span>e difference is called the common difference.
</span><span>If the numbers in the sequence follow a pattern were the next term is found by multiplying by a constant called the common ratio, r, then the sequence is geometric sequence.</span>
You have to find the slope and where it intercepts at
FOIL this out. 3x*x = 3x^2; 3x*8= 24x; -8*x = -8x; -8*8=-64. Combine like terms to get
5.476 rounded to the hundrdths is
5.48
