Answer:
B
Step-by-step explanation:
Where f(x) and g(x) intersect on the x- axis the value of y is zero
Equate either of the 2 functions to 0 and solve for x
Using f(x) = 8x² - 2, then
8x² - 2 = 0 ( add 2 to both sides )
8x² = 2 ( divide both sides by 8 )
x² = =
Take the square root of both sides
x = ± = ±
Hence k = → B
The polynomials are closed under subtraction when polynomial 5x − 6 is subtracted from is
will be a polynomial.
Polynomial is an algebraic expression that can involve variables with nonnegative integer terms and constants.
Given
Polynomial 5x -6 and .
Similar terms are terms having the same variables with the same degree.
- When we subtract polynomials, we combine like terms: 3x² is the only x² term.
- We have -6x and subtract 5x from it; this gives us -11x.
- We have 2 and subtract -6 from it; when we subtract a negative, we add the opposite, which means we have 2--6=2+6=8.
Therefore,
The polynomials are closed under subtraction when polynomial 5x − 6 is subtracted from 3x2 − 6x+ 2 is;
Hence, the polynomials are closed under subtraction when polynomial 5x − 6 is subtracted from is
will be a polynomial.
