Can someone plz help me with this questions?!

Exponential growth function

Step-by-step explanation:

The table below represents some function between x and y:

x -  4  -  5   -   6   -    7  

y - 15  - 90 - 540 - 3240  

We are required to find if it's exponential growth, decay, or neither.

An exponential function is identified because each term is calculated as the previous term multiplied by a constant factor.

The values of x grow in increments of 1 and the values of x grow by a factor of 90/15 = 6, 540/90 = 6, 3240/540 = 6

Since there is a common factor and it's greater than 1, the function is exponential growth.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
