X
let's discuss for a quick scaling paragraph
so will start off with the graph with some points that will call for facts
and in the table for here we had the experience associated with this type of experts function
nice
lets a week to find other functions eubanks
to be three times af of x
well that's gonna do exactly what we expect
that's going to multiply all the while values by two
to filling in this column
we're going to see the why values double
now before we look at this graphically
but if we also define a function expects
to be what half f_ of x_
in the sleeves act that we expect you to multiply all the white are used by a half
noticed exchange is on the output
so
are outputs have been changed nothing with the inputs
mostly what happens graphically
she saw that this was a graph of f_ of x_
let's look at these jia vax which was two times after that x
all the white guys have been double
so this is what we call a vertical stretch because it looks like the craft is being stretched
away from the x-axis
does it still has all the same inputs
but all the outputs have been double
that's whether they're positive or negative so they're moving away from the x-axis
dole we multiplied by the one-half
paragraph looks like it was compressed towards the x-axis
because all of our why values have actually been cut path
does we call it vertical compression
and vis arkin changes all the output they come from multiplying the function by some
constant values
at the values larger than what it stretches it division between zero one e compresses
it happens to be a negative value that we have a reflection
