Option #1:

f(4), this means that x = 4
To find f(4), substitute/plug in 4 into "x" in the function:
Plug in 4 into "x" since x = 4


f(4) = 2
Option #2:

The answer is 10.7 b/c 8 times three is 24 and then you divide the number 257 by 24
<span>The decay of 277 mg of an isotope is described by the function
A(t)= 277e-0.019t,
where t is time in years.
To find the amount left after 64 years,
We substitute t = 64 in the expression.
</span>A(t=64)= 277e-0.019(64)
or A(t=64) = 277 * e-1.216
= 277 * 0.29
= 82 mg
