Question

I need help with the function plz!!

Answer 1

y=4

the common ratio between the number sequence is 4

i solved it by taking 512 and dividing it by the previous number 128 and i did the same to the rest of the numbers and found the common ratio of 4

Answer 2

`2048 *( (1)/(4) ) {}^(x)`

Explanation:

Objective:Functions

The table of values range and domain isn't proportional so the answer is exponential.

A exponential function is represented by

`ab {}^(x)`

The y values are decreasing by a common ratio of 4 so our b(our base) cant be negative so it will be

`(1)/(4)`

b=1/4 so plug that in our expression.

`a( (1)/(4) ) {}^(x)`

Let plug in 1,512.

`a( (1)/(4) ) {}^(1) = 512`

`(1)/(4) a = 512`

`a = 2048`

So our function is

`2048 * ( (1)/(4) ) {}^(x)`
