4S
recursive formula
relates each term to the term before it
Explicit formula
describes the nth term of the sequence
Parallel lines
Same slope, different y-intercept
geometric sequence explicit formula
Positive slope
increases from left to right
exponential function
a function with the general form y=ab^x
power of a power
when raising a power to a power multiply exponents
systems of linear equations that have infinite number of solutions have.....
same slope, same y-intercept
The last step to writing an explicit or recursive formula is to?
Check to make sure the formula generates the sequence
systems of linear equations that have no solution have....
same slope, different y-intercept
formula for axis of symmetry of a quadratic function in standard form
x = -b/(2a)
Rise over Run
slope
Perimeter of any polygon
sum of all the sides

exponential growth formula
3 rules for Standard form of a linear equation
1) A can not be negative 2) A,B,C can not be fractions or decimals 3) A and B can not BOTH be zero
Which variable represents the y-intercept in slope intercept form
B
b^1/2
same as the square root of b

negative exponent property
A nonzero base raised to a negative exponent is equal to the reciprocal of the base raised to the opposite, positive exponent
How to find the vertex of a quadratic function in standard form
1) the x value is the x value for the axis of symmetry 2) plug the x value into the quadratic function and solve for y.
