Answer:
f(x) and g(x) are closed under multiplication because when multiplied, the result will be a polynomial.
Step-by-step explanation:
The set of all polynomials is <em>closed</em> under addition, subtraction, and <em>multiplication</em>, because performing any of these operations on a pair of polynomials will give a polynomial result.

<em>Comment on the question</em>
The wording is a bit strange, because f(x) and g(x) are elements of a set (of polynomials), so cannot be said to be "closed." "Closed" is a property of a set with respect to some function, it is not a property of an element of the set.
The graph of a cubic function has its ends in opposite direction.
A cubic function with positive coefficient rises towards right and falls towards left.
A cubic function with negative coefficient rises towards left and falls towards right.
The graph attached below shows the parent cubic function y = x³
Because the angles in all triangles must add up to 180 degrees the third angle measurement will be 90 degrees. Since the angle is 90 degrees it is automatically a right triangle.
Answer:
5-(-5)/1-(-1)=10/2=5 slope
y-(-5)=5(x-(-1))
y+5=5(x+1)
y+5=5x+5
y=5x
