Answer:
range ={-6,-2,4,8}
Step-by-step explanation:
The given function is

The domain is given as:
domain = {-4,-2, 1,3}
To find the range, we plug in the domain and solve for the corresponding range value.
When x=-4,

When x=-2,

When x=1,

When x=3,

Therefore the range is {-6,-2,4,8}
Answer:
990 TS / 45 S = R
R = 22
Step-by-step explanation:
Assuming that the blank space is a plus
2x^2+12x-14=0
isolate x
(2x^2+12x)-14=0
undistribute 2
2(x^2+6x)-14=0
take 1/2 of 6 and square and add negative and positive
2(x^2+6x+9-9)-14=0
factor perfect squrae
2((x+3)^2-9)-14=0
distribute
2(x+3)^2-18-14=0
2(x+3)^2-32=0
2(x+3)^2=32
divide 2
(x+3)^2=16
sqrt
x+3=+/-4
minus 3
x=+/-4-3
x=-7 or 1
