What is the range of the function f(x)= -2(6^x)+3?

a) (-infinity, -2]
b) (-infinity, 3]
c) [-2, infinity)
d) [ 3, infinity)

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

i just took the test, the correct answer is .. 31.5 in.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
