Rational and Exponential Functions

Rational and Exponential Functions

1. Rational Function: "A function that is the ratio of two polynomials."

2. Horizontal & Vertical Asymptotes of Rational Functions: "A line that continually approaches a given curve, but does not meet it at any finite distance."

3. Exponential Function: "A function whose value is a constant raised to the power of the argument, especially the function where the constant is e."

4. Continuous Compounding: "The process of earning interest on top of interest."

5. Compound Interest Formula: "P=principle amount (initial investment), R=annual interest rate (as a decimal), N=number of times the interest is compounded each year."

6. Decay factor of an exponential function: "The percentage by which the original amount will decline."

7. Growth factor of an exponential function: "When the growth rate of the value of a mathematical function is proportional to the function's current value."

8. Exponential decay function: "An original amount is reduced by a consistent rate over a period of time.."

9. Initial amount for an exponential function: "The initial amount is the number which you start off with."

10. Y-intercept of an exponential function: A feature on a graph

11. End behavior of a graph with asymptotes: "unction is referred to the behavior or tendency of a function or polynomial when it reaches towards its extreme points."

12. Horizontal Asymptotes of Exponential Functions: "graph goes as x heads off to the side"
