Answer:
Step-by-step explanation:
let x=11.510510510...
multiply by 1000
1000x=11510.510510...
again multiply by 1000
1000,000 x=11510510.510510...
subtract
999,000 x=1,1 49 9,000
x=11,499,000/999000=3,833,000/333,000=3833/333
333 ) 3833 (11

Given:
The given function is
To find whether the function is growth or decay and the growth of decay.
Formula:
The function is said to be an exponential growth, if the value of a > 0 and r > 0
Again, the function is said to be an exponential decay, if the value of a > 0 and 0 < r < 1.
Now,
Thus, the value of a > 0 and r > 0, then the given function is an exponential growth function.
Therefore,
The given function is an exponential growth function.
