Term
Definition
base   The number that is going to be raised to a power.  
🗑
compound interest   Interest that is paid on both the principal and the previously accrued interest.  
🗑
exponential growth   Growth whose rate becomes ever more rapid in proportion to the growing total number or size.  
🗑
interest   An amount paid which is a percentage of an initial value (principal).  
🗑
linear function   Any function that graphs to a straight line and can be written in the form y=mx+b and ax+by=c.  
🗑
relationship   A set of input and output values, usually represented in ordered pairs.  
🗑
Commutative Property   A property that states that two terms can be added, then the order may be reversed with no effect on the total. (a+b=b+a) A property that states that two terms can be multiplied, then the order may be reversed with no effect on the total. (ab=ba)  
🗑
exponent   It is written as a small number to the right and above the base number that determines how many times to multiply the base with itself.  
🗑
factoring   2y+6 = 2(y+3), so the factors of 2y+6 are 2 and (y+3).  
🗑
linear equation   An equation in the form y=mx+b or ax+by=c whose graph is a line.  
🗑
period   The length from one peak to the next (or from any point to the next matching point) of a periodic function.  
🗑
scientific notation   Where a number is written in two parts: First: just the digits (with the decimal point placed after the first digit),×10 to a power that will put the decimal point back where it should be.  
🗑
exponential function   A function whose value is a constant raised to the power of the argument, especially the function where the constant is e.  
🗑
function   A relationship in which for each input value there is one and only one output value.  
🗑
linear growth   Growth by the same amount in each time step. For example you might have something that is 5 inches long on Monday morning and then 8 inches long on Tuesday morning and then 11 inches long on Wednesday morning and so on. So it is growing by 3 inches a day.  
🗑
principal   Initial investment or capital.  
🗑
simple interest   Interest paid on the principal alone.  
🗑
