y = -x² + 9
the x-intercepts are x = - 3 and x = 3 hence the factors are
(x + 3 ) and (x - 3 )
polynomial is the product of its factors
y = a(x - 3 )(x + 3) ← ( a is a multiplier )
from the end behaviour the parabola opens down and is a maximum and so the value of a is negative
y = -(x - 3)(x+3) = - (x² - 9 ) = - x² + 9
1 pint = 2 cups
2 pint = 4 cups
3 pint = 6 cups
3 & 1/2 = 7 cups

Answer:
90
Step-by-step explanation:
87 is closer to 90 than to 80, so it rounds to 90 when rounded to the nearest 10.
Answer:
The answer to your question is below
Step-by-step explanation:
1.- Domain is all the possible values that the independent variable can take.
The function given can to all the real numbers, so,
Domain = R
2.- Range is all the possible values that the dependent variable can take.
The function given can take all the real numbers, so,
Range = R
3.- Inverse function
x = 1/2y + 1
2x = y + 1
y = 2x - 1
Domain = R
Range = R
