Answer:
Step-by-step explanation:7
The exponential equation
is equivalent to the log form equation
The base of the log is the same as the base of the exponent. The 8 inside the log argument is the right hand side of the original equation. The goal with logs is to isolate the exponent, so that's why 3 is on its own side
One way: log(A)-log(B) = log(A/B) right?
So, log( x^2-9/(x+3))
Now x^2-9 = (x+3)*(x-3), and x^2-9/(x+3) = x-3,
so log(x^2-9)-log(x+3) = log(x-3),
Indeed for all x but for x = -3, but probably no one asks you about that detail?
The situation which can be defined using an exponential function is "The number of bacteria decreases by 7% each hour".
<h3>What is an exponential function?</h3>
An exponential function is used to represent a situation in which values of an event do not increase at a constant or linear rate.
From the above,
- The value of the stocks decreased by $100 last year is a linear function.
- The number of bacteria increases by 700 each hour is a linear function.
- The value of the stocks increases by $10 every year you own them is a linear function.
