g(x) is 2x²
this is so because.
when x= 2
g(x)= 2×2²=2×4=8
also when x= (-2)
g(x) =2×(-2)²=2×4=8
Also as per the graph. (1,2) and (-1,2) lies on g(x)
when x=1
g(x) =2(1)²=2
when x=(-1)
g(x) =2(-1)²=2
Other Ootion will not give correct result for (1,2),(-1,2) ,(2,8),(-2,8)
Hope it helps...

The magnitude of this number is far from 1, so it's low correlation
Since it's negative, so it's low negative correlation
Answer:
-2, (-5 is extraneous)
Step-by-step explanation:
assuming √(x+6) -4 =x
√(x+6) = x+4
square both side
x+6 = (x+4)^2
x+6 = x^2+8x+16
x^2+7x+10=0
(x+2)(x+5) = 0
x = -2, -5
put -5 back into org equation and it is not true
√(-5+6) -4 ≠ -5
Answer:
a) Table and graph showed
b) The distance will be 231 miles
c) Yes
Step-by-step explanation:
We know the van gets 22 mi/gal, so the distance D in miles traveled by the van can be expressed as
D(g)=22g, being g the number of gallons of gas used
a) The graph of the function D and its corresponding table of values is shown below.
b) If the van used g=10.5 gallons of gas, the distance would be:
D(10.5)=22 x 10.5 = 231 miles
c) The values of g are real in nature because they represent the amount of gas consumed by the van and it can be any real positive number. Being D a linear function of g, it also happens to take positive real values. Then it makes sense to connect the points with lines.
= ( 3x² + 3x + 5 ) ( 6x + 4 )
= 18x³ + 18x² + 30x + 12x² + 12x + 20
= 18x³ + 30x² + 42x + 20
