Answer:
Mrs. Delgado purchased 6 notebooks and 2 packages of pens.
Step-by-step explanation:
Given that Mrs. Delgado purchased notebooks at 2 for $ 5 and pens at $ 2 per package, and she spent $ 19 for a total of 8 items, to determine how many notebooks and pens did she buy the following calculation must be performed:

Required
To determine if it is an exponential function, we have to write in form of

If we're able to do so, then the function is an exponential function.
If otherwise, then it is not

Apply Law of indices

Express 5^3 as 125

Factorize the exponent of 5

Express 5^2 as 25

This can be rewritten as:

By comparing the above to 
We have that


Since, we've be able to express the function as 
Then,
is an exponential function
