Find the incorrect statement
The degree of this function is 5
There is a zero at 3 with multiplicity 2
The graph crosses the x-axis at −2
The limit as x approaches -∞ is ∞
Which choice is correct?
This function has an even degree

The zero at −2 has even multiplicity.
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)
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)
