Your best bet is to make a table of the x and y values.
Then plug -2, -1, 0, 1, and 2 in for x, into the equation to get the y values. That's how you get your points.
Answer:
P(x) = 
- 7x² + 12
Step-by-step explanation:
Given zeros x = 2, x = - 2, x = 
, x = -
Then the factors are (x - 2), (x + 2), (x - ), (x + )
and the polynomial is the product of the factors, that is
P(x) = (x - 2)(x + 2)(x - )(x + ) ← expand in pairs using FOIL
= (x² - 4)(x² - 3) ← distribute
= - 3x² - 4x² + 12 ← collect like terms
= - 7x² + 12
Answer:
Q4: First, third, fifth
Step-by-step explanation:
I'm pretty sure question 5 is the first, and fourth one.
Answer:
12 _3/4
Step-by-step explanation:
3/4 + 1/2 + 2 = 3_1/4
16 cups in a gallon
16-3_1/4
=12_3/4
Answer:
r^2=(A/pi)
Step-by-step explanation:
if A=pi*r^2 then maybe dividing by pi to get r^2 alone says r^2=(A/pi) or to get rid of the exponent you may square root each side so r=(sqrt(A/pi))
