 If x2 or y2 is present (but NOT both) parabola x2+y2=k ax2+ay2=k circle ax2+by2=k or by2+ax2=k, a cannot equal b ellipse ax2-by2=k, by2-ax2=k (a can = b) hyperbola Inverse variation (i.e. in the form xy=k) equilateral hyperbola reflect over x-axis (x,-y) Reflect over y-axis (-x, y) Reflect over y=x (y,x) Reflect over y=-x (-y,-x) Reflect over x=a (2a-x, y) Reflect over y=b (x, 2b-y) Reflect through (0,0) (-x,-y) Rotate 90 degrees with respect to origin (-y,x) Rotate 180 degrees (origin) (-x,-y) Rotate 270 degrees (origin) (y, -x) Ta,b (x+a, y+b) Dilation of k (origin) (kx, ky) -y=f(x) or y=-f(x) reflect over the x-axis y=f(-x) reflect over the y-axis y=If(x)I (absolute value of f(x)) reflect pieces below the x-axis to above y=f(IxI) Duplicate right to left (erase left side of graph, and then reflect right side over the y-axis) y=f(x-h) Translate right h units (h>0) Translate left h units (h<0) y-k=f(x) Translate up k units (k>0) translate down k units (k<0) y=c*f(x) A vertical stretch-multiply y-coordinates only by c (c>1) A vertical shrink-multiply y-coordinates only by c (01) A horizontal stretch-multiply x-coordinates only by 1/c (00 2 real, unequal roots b2-4ac is a perfect square rational roots b2-4ac is not a perfect square irrational roots The composite of two line reflections over parallel lines is a translation The composite of two intersecting line reflections is a rotation the composite of two line reflections over perpendicular lines is a 180 degree rotation (half turn) The composite of two line reflections over the same line is the identity transformation Glide reflection a transformation that is the composite of a line reflection and a translation whose direction is parallel to the line reflection Isometry a transformation that preserves distance direct isometry isometry that preserves orientation opposite isometry isometry that reverses orientation line reflection (what type of isometry?) opposite isometry translation direct isometry rotation (isometry? what type if so?) direct isometry dilation (isometry?) NOT an isometry
