This graph has a root of multiplicity 1 and a root of multiplicity 2
Because the zeroes of this graph are -2 and 1, the equation must be
f(x)=a(x+2)(x-1)
To find a, we use the point in the graph (2,8)
8=a(2+2)(2-1)
8=a(4)(1)
8=4a
a=2
f(x)=2(x+2)(x-1)
Because the zeroes of this equation are -1, 1(with multiplicity 2), and 5 the equation must be
f(x)=a(x+1)(x-1)^(2)(x-5)
To find a we use the point in the graph (0,-10)
-10=a(0+1)(0-1)^(2)(0-5)
-10=a(1)(-1)^(2)(-5)
-10=-5a
a=2
f(x)=2(x+1)(x-1)^(2)(x-5)
Because the zeroes of this equation are -3 (with multiplicity of 2) and 2, the equation must be
f(x)=a(x+3)^2(x-2)
To find a, we use the point in the graph (0,-9)
-9=a(0+3)^2(0-2)
-9=a(9)(-2)
-9=-18a
a=.5
f(x)=.5(x+3)^2(x-2)
This is a 4th degree graph with a root of multiplicity2 and 2 roots of multiplicity 1
This graph has 2 roots of multiplicity 1 and a root of multiplicity 2
Because the zeroes of this equation are -2,0 (with multiplicity 3), and 2, the equation must be
f(x)+a(x+2)(x)^3(x-2)
To find a, we use the point in the graph (1,9)
9=a(1-2)(1-0)^3(1+2)
-9=a(-1)(1)^3(3)
-9=3a
a=-3
f(x)=-3(x+2)(x)^3(x-2)
Because the zeroes of this equation are -3, -2 and 1 (with multiplicity 2) the equation must be
f(x)=a(x+2)(x+3)(x-1)^2
To find a, we use the point in the graph (0,-6)
-6=a(0+2)(0+3(0-1)^2
-6=a(2)(3)(-1)^2
-6=6a
a=-1
f(x)=-(x+2)(x+3)(x-1)^2
This is a 5th degree graph with a root of multiplicity 3 and 2 roots of multiplicity 1
This graph has 2 roots of multiplicity 1
