10 cards from this deck
f(x)=xrf(x) = x^rf(x)=xr where rrr is rational
If x2>x1x_2 > x_1x2>x1 then f(x2)>f(x1)f(x_2) > f(x_1)f(x2)>f(x1)
f(−x)=−f(x)f(-x) = -f(x)f(−x)=−f(x) (rotational symmetry about origin)
f(−x)=f(x)f(-x) = f(x)f(−x)=f(x) (reflective symmetry about y-axis)
R∖{0}\mathbb{R} \setminus \{0\}R∖{0} (all reals except zero)
R+\mathbb{R}^+R+ (positive real numbers only)
The nnnth root of aaa
R+∪{0}\mathbb{R}^+ \cup \{0\}R+∪{0} (non-negative numbers)
R\mathbb{R}R (all real numbers)
Horizontal: y=0y=0y=0, Vertical: x=0x=0x=0 (both axes)
