Function or Not?
Not a function
Linear or nonlinear ?
linear
(1,5) ( 2, 7) (0-2) (-2, -5)
SHOW BOARDS
y = 2x + 3
Show boards
Write the equation
y = 15x - 9
or
y = 15x + -9
Function or Not?
Function
Linear or nonlinear?
nonlinear
Graph the following points:
(0, -2) (2,2) (-2,0)
SHOW BOARDS
y = -x - 6
Write the equation:
y = 3x + 0
or
y = 3x
Function or not?
(-2, 0) (-1, 0) (0, 0) (1, 0) (2, 0)
Function, none of the inputs (x values) repeat.
Linear or nonlinear? Why?
Nonlinear because there isn't a constant rate of change.
Graph from the table:
SHOW BOARDS
y = -2x2 + 3
Show boards
Write the equation
y = 1/2x + 2
Function or not?
Function.
Linear or nonlinear? Why?
Linear, constant rate of change.
x change is + 3
y change is + 2
Graph from the table:
SHOW BOARDS
y = 7 - x
Write the equation:
y = 6.5x
or
y = 6.5x + 0
Function or not?
Not a function, there are two outputs for the input 2.
Linear vs Nonlinear? Why?
Nonlinear, not a constant rate of change.
Graph the following
SHOW BOARDS
y = 4+ 1/2x2
Write the equation:
y = 5/2x + -2
or
y = 5/2 - 2
