Could anyone help me with this please?

hopefully this helps??

coordinates 1,-7.. 2,-5. 3,-3. 4,-1. 5,1 and so on

Step-by-step explanation:

2n-9=x

(2•1)-9=-7

(2•2)-9= -5

(2•3) -9= -3

(2•4) -9= -1

(2•5) -9= 1

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
