Functions that are entered after the argument, such as 2, -1, !, o, r,
and conversions
Powers and roots such as 2^5 or 5x

(After ZStandard or ZDecimal)
– Ymin = -31
Xmin = -47
– Ymax = 31
Xmax = 47
– Yscl = 10
Xscl = 10

(After window centered at point (a,b))
Xmin = a – 47
– Ymin = b – 31
Xmax = a + 47
– Ymax = b + 31
Xscl = 10
– Yscl = 10

Xmin = unchanged
–
Ymin = min(Yn) for
Xmin < X < Xmax
Xmax = unchanged
– Ymax = = min(Yn) for
Xmin < X < Xmax
Xscl = unchanged
– Yscl = unchanged
Allows you to see y values for all of the x’s in
the domain of the graph
• ZSquare
–
–
Adjusts the size of the window so that the x
dimension and the y dimension are
proportionate (e.g. a circle looks like a circle
Center of the graph is unchanged
• ZBox
