The given function is f(x)=2x^3+2x^2-x. In this case, the highest degree among the terms is 3. According to the Fundamental Theorem of Algebra, the number of zeros or roots of the equation is equal to the highest degree among the terms. Hence for every value of y, there are 3 equivalent x's. The answer thus is B. It is a many-to-one function.
That's what I did and since the zeros would be -5 and 3 the answer would be 3 since it can't be a negative
<u>To prove the trigonometric equation:</u>
We know that 
, substitute this in place of 1.
Multiply each term of the first term with each term of the 2nd term.
Group like terms together.
= LHS
RHS = LHS
Hence proved.
Multiply each term in the parenthesis by -4
-4 • 6n-4•(-5)+3a
Calculate the product -4•6n= -24n
Multiply the numbers -4•(-5)= +20
Then put every thing together
Final Answer: -24n+20+3a
Perimeter = 2L + 2w
in this case, L = 3w - 2 and perimeter = 28.
so, 28 = 2L + 2w. or 14 = L + w. or substitute for L: (3w - 2) +w =14
or 4w - 2 = 14. 4w = 12. 12/4 = 3 = w.
The width = 3 inches; and the length = (3x3 -2) 7 inches.
