Answer:

Step-by-step explanation:

2/3 • 1/5 = 2/15
'of' always means multiplication.
-2.4x^2 -1.5x-11.4 is the answer
Assuming the function is

, and not

which would be its own Maclaurin polynomial right away.

Recall the geometric power series,

where

. Replace

and we have

and so

We want the 4th degree polynomial, so
