Graph A because a graph of non proportional relationship will not pass through the origin (0,0) hope this helps! Remember to give me a like if it did please and thank you!
You can compare them mentally! A fraction ia divided into 2 parts, however a decimal is not! Also the strategies you have to use are different. When finding the product/sum/quotient of a fraction you need to find a common denominator. But, with a decimal all you need to do is place the decimals correctly!
Since
are in arithmetic progression,




and since
are in geometric progression,




Recall that


It follows that

so the left side is

Also recall that

so that the right side is

Solve for
.

Now, the numerator increases more slowly than the denominator, since


and for
,

This means we only need to check if the claim is true for any
.
doesn't work, since that makes
.
If
, then

If
, then

If
, then

There is only one value for which the claim is true,
.
