Answer 1

The table shows the number of books donated to a library each month. The growth is exponential. Suppose the growth continues at the same rate.

How many books were donated to the library in Month 8?

Round to the nearest whole number.

Enter your answer in the box.


Month 0 1 2
Number of books 80 100 125

Answer 2

\[f(x) = a \times r^x\]
where \(a\) = initial value, \(r\) = common ratio

Answer 3

Therefore, please state what is the initial value and then find the common ratio by dividing the number of books in the first month by the number of books in the numbers of books that were started with.

Answer 4

Do you seem to understand where this is going?

Answer 6

If the growth is exponential, isn't that of the form y=e^(something times x) ? Doesn't the word exponential refer to 2.7 ?
f(x)=a×r^x yes there is x as the power but is that the same as "exponential" ? I see these words bandied around a lot, I'm, as usual, baffled.
