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.
Answer:
The minimum point is (4,-3)
Step-by-step explanation:
we know that
If the new equation is
y=f(x-5)
then
The Rule of the translation is
(x,y) -----> (x+5,y)
That means ----> The translation is 5 units at right
so
(−1,−3) ----> (-1+5,-3)
(−1,−3) ----> (4,-3)
Well, we know that 1 hour is 60 minutes which means 2 hours is 120.
so to find the answer we turn 40% into a decimal which would be .40
Take .40 and multiply that by 120.
.40 * 120 is 48
40% of 2 hours is 48 minutes.
Hope this helps!

Answer: 1.28544 x 10^5 (ten to the 5th power)</h3>
Step-by-step explanation:
4 x 103 = 412, 3 x 104= 312
412 x 312 = 128,544
number has to be between one and ten and show significant digits. the decimal has to be moved five tome to the left creating the number 1.28544. to move the decimal back you have to multiply by 10 to the 5th power. Yielding 1.28544 x 10^5
