The domain of the graphed function is [-3, 2)
<h3>How to determine the domain and the range?</h3>
From the given graph, we have the following highlights:
- Minimum x value = -3 (closed circle)
- Maximum x value = 2 (open circle)
Open circles are represented with () while closed circles are represented with []
Hence, the domain of the graphed function is [-3, 2)

#SPJ1
Answer:
#1: x = 3; #2 c = 1/2; #3 = x = 22; #4 is correct (x = -8)
Step-by-step explanation:
for the first equation everything was right until 22x = 66
after
22x = 66
you must divide everything by 22
x = 3
that is for #1
for the second equation you copied down the question wrong
the negative is still there
6c - 8 - 2c = -6
combine 6c and -2c
4c - 8 = -6
the negative remains on the 8
add 8 to both sides
4c = 2
divide 4 to both sides
c = 2/4 or just 1/2
for the third equation you must first combine like terms
-3x + 25 + x + 21 = 2
combine -3x and x & 25 and 21
-3x + x = -2x
25 + 21 = 46
-2x + 46 = 2
then subtract 46 from both sides
-2x = -44
now divide both sides by -2
x = 22
that is your answer
number four should be correct
K/6+8=5 C/2+5=1
K/6=-3 C/2=-4
K=-18 C=-8
9+A/6=8 D/4-9=-3
A/6=-1 D/4=6
A=-6 D=24
This is a special product factorization.
If the first term is a perfect square, the last term is a perfect square, and the middle term is twice the product of their square roots then you get the form
(a + b)^2.
SO....(5x + 9)^2 or (5x +9)(5x +9)
