## 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.

f(x)=-0.1x^3+0.2x^2+2x-2

So close! I used y = -1/10(x-5)(x-1)(x+4) which expands to y = -0.1x^3+0.2x^2+1.9x-2. Pretty sure I wouldn’t be able to tell them apart! Great job.

y=(4.8sinx) – 2

y=(4.8sum a(n=0)*(-1)^n*x^(2n+1)/(2n+1)!)-2(a=3)

oops its the negative value of it
