Answer:
vertex: (-2, 4)
Step-by-step explanation:
Use your regression calculator to find the parameters of the quadratic model.
The vertex form equation is ...
y = -3(x +2)^2 +4
so the vertex is (-2, 4).
__
The standard form equation is the expansion of the above:
y = -3x^2 -12x -8
3 is what percent out of 8
Can also be written as 3/8
To turn a fraction into a percentage, divide the numerator by the denominator and them multiply by 100
3/8 = 0.375
0.375 x 100 = 37.5
37.5%
(0,7) , (7,8)
Y-intercept is at (0,7) and the slope is 1/7 so from the y intercept, go up 1 and over 7.
Whats the value what ever it is its divided by three
You do the sum backwards,
36-16=17
17x3=51
Then you check it to make sure,
51/3=17
17+19=36
:) hope this hepled x
