## On to the Challenge!

Can you create the following graph using desmos.com or some other graphing tool? If you’re victorious, leave us a note in the comments when you’re done.

**Note: This set of 4 graphs was not made with trigonometric functions. Can you replicate it?**

Nicely done!

y=(x-1)^2-1 {0≤x≤2}

y=-(x-3)^2+1 {2≤x≤4}

y=(x-5)^2-1 {4≤x≤6}

y=-(x-7)^2+1 {6≤x≤8}

{0<x<2} (x-1)^2 = (y+1)

{4<x<6} (x-5)^2 = (y+1)

{6<x<8} (x-7)^2 = -(y-1)

{2<x<4} (x-3)^2 = -(y-1)

Put in each of these equations for the "bolded"/"doubled" curve color.

y=(x-1)^2-1 {0≤x≤2}

y=-(x-3)^2+1 {2≤x≤4}

y=(x-5)^2-1 {4≤x≤6}

y=-(x-7)^2+1 {6≤x≤8}

Sooo I got:

y=(x-1)²-1 {0≤x≤2}

y=-(x-3)²+1 {2≤x≤4}

y=(x-5)²-1 {4≤x≤6}

y=-(x-7)²+1 {6≤x≤8}

darn it this is hard

HOW DO YOU DO THIS CRAP???
