(-3, -188), (-2, -35), (0,7), (1, 16), and (2, 17) there we go lol

I'm not sure if this is the best approach, but here's one idea... Since it passes through (0,7), it has a y-intercept of 7.$\Large\bf y=ax^4+bx^3+cx^2+dx+7$

We can setup a system of equations using the other points provided.$\Large (1,16):$$\Large\bf 16=a+b+c+d+7$Then another point gives us:$\Large\bf (2,17):$$\Large \bf 17=a2^4+b2^3+c2^2+d2+7$
