Answer:
X=7
X=2
Step-by-step explanation:
Ok so domain is all allowed numbers
look at deonomenator and don't allow any numbers that will make it zero
none
that means
domain=all real numbers
vertex
in form
y=a(x-h)^2+k
(h,k)=vertex
we have
y=-2(x+3)^2-1
h=-3
k=-1
vertex=(-3,-1)
range
the vertex opens down so max is y=-1
y≤-1
domain is all real
vertex is (-3,-1)
y≤-1
C
A vertical line i believe since x is constant
Each notch should equal -3 (the difference between -10 and -4 is 6), meaning that the blue dot should be -19
The only linear equation is choice d
