quadratic functions
this form of a quadratic function is written as y=2x^2+4 (hint:starts with an s)
standard
An exponential function has a variable in this part of expression
Exponent
This famous irrational number is used to calculate the circumference of a circle
pi
Parallel lines have this in common
Slope
In an arithmetic sequence the difference between terms is called this
Common difference
The graph of a quadratic function is called this shape.
parabola
In the function f(x)=3(2)^x the base is this number
2
this kind of number cannot be written as a fraction or repeating decimal
Irrational number
Perpendicular lines have slopes that are this
Negative reciprocals
