The functions would be:

D. y=x³

We can check it out.

(1,1); x=1; y=1 ⇒1=(1)³=1*1*1=1

(2,8); x=2; y=8 ⇒8=(2)³=2*2*2=8

(3,27); x=3; y=27 ⇒27=3³=3*3*3=27

(4,64): x=4; y=64 ⇒64=4³=4*4*4=64

(5,125); x=5; y=125 ⇔ 125=5³=5*5*5=125

**Answer:**

5

**Step-by-step explanation:**

because 4/5=0.8

and 5×0.8 = 4

**Answer:**

Because there is no y value, this line would not have a slope.

**Step-by-step explanation:**

In order for a line to have a slope, there must be 2 variables in the equation.

Answer:

Kindly check attached picture

Step-by-step explanation:

Given the following :

First term (a) = 3

Second term = - 6

third term = 12

Fourth term = - 24

We can obtain the common ratio of the series using the relation :

(2nd term/ 1st term) = (3rd term/2nd term) = (4th term/ 3rd term) =....

(-6/3) = (12/-6) = (-24/12)

-2 = - 2 = - 2
