Parent Equation
O The simplest form of any functionO Each parent function has a
distinctive graphO We will summarize these in the next
few slides

Vertical TranslationsO Positive Shift (Shift up)
O Form: y=f(x)+b where b is the shift up
O Negative Shift (Shift down)O Form: y=f(x)-b where b is the shift
down

Horizontal TranslationsO Shift to the right
O Form: y=f(x-h) O The negative makes you think left,
but actually means right hereO Shift to the left
O Form y=f(x+h)O This would shift to the left of the
origin

Vertical Stretch and Compression
O If y=f(x), then y=af(x) gives a vertical stretch or compression of the graph of f
O If a>1, the graph is stretched vertically by a factor of a
O If a<1, the graph is compressed vertically by a factor of a

Horizontal Stretch and Compression
O If y=f(x),then y=f(bx) gives a horizontal stretch or compression of the graph of f
O If b>1, the graph is compressed horizontally by a factor of 1/b
O If b<1, the graph is stretched horizontally by a factor of 1/b

ReflectionO If y=f(x), then y=-f(x) gives a
reflection of the graph f across the x axis
O If y=f(x), then y= f(-x) gives a reflection of the graph f across the y axisl
