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
Answer:
1/4 times 6= 1 1/2
Step-by-step explanation:
Answer:
its n+20-55-35
Step-by-step explanation:
4. A graph shows the solutions to be
x = -3/2, -1, 0
The root at -1 has multiplicity 2. That is, the factoring is
x(2x+3)(x +1)² = 0
5. A graph shows the real roots to be
x = -1, 2
Dividing these from the polynomial gives the quadratic
x^2 +3
which has roots
x = ±i√3
The factorization is
(x +1)(x -2)(x² +3) = 0
and the solutions are
x = -1, 2, -(√3)i, (√3)i
Answer:
20
Step-by-step explanation:
F (-7) = -6x -22
F (-7) = -6 (-7) - 22
F (-7) = 42- 22
F (-7) = 20
hope that helps
