Check : Make­up/Late Work
L.T. : I will identify quadratic functions by the features
of their graphs. I will graph a quadratic function.
Warm­up : Graph each function. Note whether it is linear or non­linear.

Quadratic Functions
Graph the quadratic function : y = x2 ­ 5x + 4
x
y
Is it linear or non­linear? What shape is it?
Does it have a y­intercept? Where?
Does it have an x­intercept? Where?
Does it have a highest point (maximum)? Where?
Does it have a lowest point (minimum)? Where?
