Yes, that is factual I believe.
Below -2: -4.5, -2.5
Between -2 and 1: 0.5, -0.5
Above 1: 1.5, 4
Hope this helps!
We have that
x² = 8y-------> y=(1/8)*x²
we know that
the equation of a parabola is of the form
y=a(x-h)²+k
in this problem
a=1/8
(h,k)--------> is (0,0)------> is the vertex of the parabola
a > 0--------> the parabola opens up
therefore
the answer is
<span>the value of a is (1/8)</span>
X=8
y=5
It's a system of equations'
Y = 2x² + 30x + 200
y = 2(x² + 15x + 100)
x² = x*x
100 ⇒ 1 x 100 ; 2 x 50 ; 4 x 25 ; 5 x 20 ; 10 x 10
200 = 2x² + 30x + 200
0 = 2x² + 30x + 200 - 200
0 = 2x² + 30x + 0
0 = 2(x² + 15x + ?)
<span>−5 ≤ x ≤ 20</span>
