Answer:
C
Step-by-step explanation:
I have attached graphs of all the equations below
A starts off increasing so it cannot be it
B is increasing after some point, so doesn't work
C works
D has a constant y after some point, so doesn't work (not increasing or decreasing)
therefore: C is the correct answer
Answer:
Step-by-step explanation:
It is important to remember that an Exponential function has the following form:
Where “b” is and
, "a" is a coefficient, "x" is the Independent variable and f(x) is the Dependent variable.
In this case, you have the following Exponential Function given in the exercise:
If the value of Dependent variable is -3, then:
So, you must substitute that value of "x" into the function:
And now you must evaluate:
1. According the Negative exponent rule:
Then:
2. Simplifying, you get:
