Explanation:
"the graph has zeros at "x=-1" and "x=0
x=-1" multiplicity 1 and " x=0 " multiplicity 2"
rArr"factors are "(x+1)" and "x^2
rArry=ax^2(x+1)larrcolor(blue)"a is multiplier"
"to find a substitute "(1,2)" into the equation"
2=a(1)(2)=2arArra=1
rArry=x^2(x+1)=x^3+x^2
graph{x^3+x^2 [-10, 10, -5, 5]}
