iI think that c because it is inside the integers are inside the rationals
f(x) has vertex = (- 1, - 5 ) and is a minimum
g(x) has vertex = (2, 3 ) and is a maximum
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = (x + 1)² - 5 is in this form with vertex = (- 1, - 5 ) and minimum
to determine if maximum/ minimum
• if a > 0 then minimum
• if a < 0 then maximum
g(x) = - (x - 2)² + 3 is also in vertex form with a < 0
vertex = (2, 3 ) and is a maximum

0.80 / 4 = 0.20
Answer: When two polynomials are multiplied, the product is always a
polynomial.
Step-by-step explanation:
The only true property for polynomials is the third options because when you do multiply polynomials, you can only get a polynomial.
For instance;
Multiply (5x – 6y) by (7x – 4y)
= (5x – 6y)(7x – 4y)
= 35x² - 20xy - 42xy + 24y²
= 35x² - 62xy + 24y²
The result is a polynomial.
The rest of the options will not always yield polynomials.
