Answer:
S(-2,12)
y= -2(x+2)²+12
Location of coordinate axes:
y=0 → x= -2±√6 (-2-√6,0) (-2+√6,0)
x=0 → y=4 (0,4)
If you factor 4x²-12x, you can divide 4x from each term.
4x² ÷ 4x = x
-12x ÷ 4x = -3
Therefore, the other term becomes (x-3) because 4x(x-3) = 4x²-12x
So all u have to do is say all the x values that have a point (the domain) and all the y values that have a point (the range). If it is continuous, like a line, then u say all the points between two points. For example the range of the bottom right is [-1,5]. If it goes to infinity or negative infinity, you say something like (-infinity,infinity). With the sideways 8 of course. Btw, (-infinity, infinity) is the domain of the bottom right ;D
(a+b)^3 = a^3+b^3+3ab(a+b)
(a+b)^3 = (-1)^3
