Which function represents g(x), a reflection of f(x) = 6 (
across the y-axis?
5
do
DO
O g(x) = -6(1)
O g(x) = -6
2 3 4
O g(x) = 6(3)
g(x) = 6(3)

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
