11. 2.1 Relations and Functions
Relation- set of ordered pairs containing input and output values
Domain- x values, set of inputs, or 1st number of ordered pair
Range- y values, set of outputs, or 2nd number of ordered pair

12. 2.1 Relations and Functions

13. 2.1 Relations and Functions
Function- a relation where each element of the domain corresponds with exactly one element of the range (vertical line test or x cannot repeat); notated f(x) = y
Independent Variable- input value, x, on the horizontal axis e.g. time
Dependent Variable- output value, y, on the vertical axis, depends on input e.g. hourly salary

19. 2.6 Families of Functions
Reflection- flips the graph of the parent function across a line
f(x)  f(-x) (reflection across y-axis)
f(x)  -f(x) (reflection across x-axis)
Dilation- multiplying the y-value of the parent function by a scalar y = af(x)
