Now that we have the function (referencing the previous problem):
q
(
t
)
=
7
2
t
+
5
4
t
4
+
6
\displaystyle {q}{\left({t}\right)}=\frac{{7}}{{2}}{t}+\frac{{5}}{{4}}{t}^{{{4}}}+{6}
q
(
t
)
=
2
7
t
+
4
5
t
4
+
6
Find the charge after 3 seconds.
q
(
3
)
=
\displaystyle {q}{\left({3}\right)}=
q
(
3
)
=
amperes
