    F(x)= x+2m ,x<-3 3m(x^2)+k ,-3≤x<1 2(x^3)-m ,x>1 ___________________________ (this is da multi-rule) ^^ Where F(x) is continuous at x=-3 ,at x=1 Find m,k

    So basically plug in x=-3 into x+2m and into 3m(x^2)+k

    Now equate them because you want them to meet at the same point for the function to be continuous -3+2m=27m+k 2m-27m=k+3 -25m=k+3 k = -(25m+3)

    Do the same thing for 3m(x^2)+k 2(x^3)-m, but at x=1

    k = -(25m+3) 3m+k=2-m 3m-25m-3=2-m -22m+m=2+3 -21m=5 m=-5/21
