Given:
f(x) is an exponential function.
To find:
The value of f(6.5).
Solution:
Let the exponential function is
...(i)
Where, a is the initial value and b is the growth factor.
We have, . So, put x=-3.5 and f(x)=25 in (i).
...(ii)
We have, . So, put x=6 and f(x)=33 in (i).
...(iii)
On dividing (iii) by (ii), we get
Putting b=1.03 in (iii), we get
Putting a=27.63 and b=1.03 in (i), we get
Therefore, the required exponential function is .
For the given conditions, we won’t get a practical solution.
<u>Solution:</u>
Given, An automobile dealer had 288 cars and trucks in stock during the month.
He must pay an inventory fee of 52 per car and $5 per truck.
He paid $849 for inventory foes.
We have to find how many cars and Trucks did he have during the month?
Now, let the number of trucks be n, then number of cars will be 288 – n
And, according to given information,
Here we got n > number of cars and trucks, which is practically impossible.
Hence, for the given conditions, we won’t get a practical solution
