Root: where a function equals zero [ f(x)=0 ]

Using the graph, f(4)=0 and f(-3)=0

Therefore the positive root is 4

And the negative root is -3

Answer:

see explanation

Step-by-step explanation:

The roots of f(x) = 0 are the points on the x- axis where the graph crosses the x- axis

(a)

The graph crosses the x- axis at (4, 0 )

Then x = 4 is the positive root

(b)

The graph has a turning point on the x- axis at (- 3, 0 )

Then x = - 3 is the negative root with multiplicity of 2
