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.
Step-by-step explanation:
<em>2 . 14 x − 42 . 9 for x = 22 . 4 .</em>
- 2.14(22.4) = 47.936
- 47.936-42.9 = 5.036
your answer is 5.036
Answer:
d
Step-by-step explanation:
Total-$31.23
explaination- you multiply 2.25 x4.8 and get 10.80 and then you multiply 2.25x7.3 and get16.43 then u add 4 to each of them and add them all up 14.80+16.43=31.23 and the 4 dollars are already included
