<h2>Answer</h2>
f(x) = 190(1.15)x
<h2>Explanation</h2>To solve this, we are going to use the standard exponential function:
Where
is the final price after
years
is the initial price
is the rate in decimal form
is the time in years
We know from our problem that the initial price is $190, so . Now to convert the rate, 15%, to decimal form, we are going to divide it by 100%, so
. Let's replace the values:
Answer:
C. All real numbers except .
Step-by-step explanation:
The domain of all polynomials is the set of all real numbers, whereas the domain of rational-polynomic functions are the set of all numbers expect for those values of so that denominator becomes zero. Hence, we need to solve for
from following expression:
The domain of the function is all real numbers except . (Right answer: C)
