F(x) = |x+3| horizontal stretch by a factor of 4

f(x)= 1/4(|x+3|)

Step-by-step explanation:

By putting this answer outside of the parenthesis, it will cut down the answer by 1/4. This stretches the parabola horizontally by decreasing the factor y.

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
