y = 3(x + 4)(x + 1)(x - 3)?
y = (x + 2)(x - 7)3
Which function might have the given graph?
f(x) = (x - 6)(x + 4)2
f(x) = (x - 6)2(x + 4)
f(x) = (x + 6)2(x - 4)
f(x) = x(x - 6)(x + 4)
Which function has zeros: x=0, x=5(multiplicity of 3) and x=-6.
f(x) = 9x(x + 5)3(x - 6)
f(x) = 3(x - 5)3(x + 6)
f(x) = -7x(x - 5)3(x + 6)
f(x) = (x - 3)(x - 5)(x + 6)
