Exponential Functions - Vocabulary
rate
(1 - growth factor) or (growth factor - 1)
a Half
1/2 or 0.50
a Third
1/3 or 0.33
a Quarter
1/4 or 0.25
Positive Correlation
A correlation where as one variable increases, the other also increases, or as one decreases so does the other. Both variables move in the same direction.
Negative Correlation
A finding that two factors vary systematically in opposite directions, one increasing as the other decreases.
decreases

Exponential Growth
The population (y) doubles
Exponential Growth Growth Factor of 2
the amount (y) Triples
Exponential Growth Growth Factor of 3
Four Times as many of the amount (y)
Exponential Growth Growth factor of 4
No Correlation
There is no relationship between data sets.
Linear Function
a function in which the graph of the solutions forms a line
Exponential Function
a function that can be described by an equation of the form y= a*b^x, where b > 0 and b ≠ 1.
growth or decay factor
the fixed multiplier
Exponent
the power to which a number, symbol, or expression is to be raised
initial value
the starting amount or y-intercept of the graph
exponential function
y=starting value(growth factor)^x
