Determine the range of the following graph

Range: [-6, 8]

Step-by-step explanation:

Range is the set of y-values that are outputted by function f(x).

From the graph we see that our y-values span from -6 to 8. Since both are closed dot, they are included in the range:

[-6, 8] or -6 ≤ y ≤ 8

how is that middle school

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
