Can someone let me know if I’m anywhere near the right answer?

I can't figure out what you're trying to solve otherwise eeveethink

#

alr so doing it with a table is a bit… 😬

#

it becomes tedious

#

and also a bit unnecessary :p

#

@sick cloud this is alg 2 right

#

now while mathematicians will say memorizing formulae is bad advice, i find it hard to describe this question easily and intuitively

#

as of now, use this:

#

$$
Vf\left(\frac{x-u}{U}\right)+v
$$

#

essentially, rewrite the equation so that it looks like this.

#

once you have done this, horizontally stretch/squish the graph by a factor of U and vertical stretch/squish it by V.

#

then, move the graph horizontally by u and vertically by v

#

so your equation would become

#

$$
\textcolor{gray}{1}f\left(\frac{x-(-4)}{-1/2}\right)-5
$$

#

so you redraw the graph scaled horizontally by -1/2 (reflect it and squish it to half of what it is); moved 4 left; and moved 5 down.

#

alternatively, you could use this which does the same thing:

#

$$
\frac{y-v}{V}=f\left(\frac{x-u}{U}\right)
$$

#

tota nox

#

so we would get

#

$$
\frac{y-(-5)}{1}=f\left(\frac{x-(-4)}{-1/2}\right)
$$

This is sad 😢

@sick cloud

#

i made a cheat sheet for how to do any of these types of questions

#

of you have any questions lmk

Can I keep this?
