what does it mean when the number is on the outside like this f(x) +- C

it means that the transformation is up or down

what does it mean when the number is on the inside like this f(x+-c)

it means that it moves left or right (it’s opposite)

what does it mean if there’s a negative OUTSIDE the parenthasis like this -f(x)?

it means it’s a reflection over the X-AXIS

what does it mean when there is a negative inside the parenthasis like this f(-x)?

it means it’s a reflection over the Y-AXIS

what does it mean when the number is outside of the parenthesis like this a f(x)?

it’s a vertical something

• if it’s greater than one it’s a VERTICAL STRETCH

• if it’s between 0 and 1 it’s a VERTICAL COMPRESSION

what does it mean when the number is inside the parenthasis before x like this f(bx)?

it’s a horizontal thing

• if it’s greater than one it’s a HORIZONTAL COMPRESSION

• if it’s between 0 and 1 it’s a HORIZONTAL STRETCH

• both are by their RECIPROCAL
