0.913 that the right one i asked my mom
i cant see the lines clearly, soo all i can say is that:
- x is the horizontal line, y is vertical
- quadrant I all positive
- quadrant II x negative, y positive
- quadrant III all negative
- quadrant IIII y positive, y negative
- for every line the point passes, it counts as 1
- each point does not have a certain order to go in the chart
sorry, but this is the best i can do for now! make sure your pictures are clear next time :D
Answer:

Step-by-step explanation:
Answer:
x^2+4x+2
Step-by-step explanation:
√4 = 2
=x^2+2x+2x+2
add the ones that are the same (2x+2x)
x^2+4x+2
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
