(I could really use help with this) A polynomial function h(x) has a zero of x = 3 – 4i with a multiplicity of one. Certain values of h(x) are given in the following table.

x h(x)
–5 0
–2 3
–1 0
1 2
4 0
7 6
10 0

If every real x-intercept of h(x) is shown in the table and each has a multiplicity of one, what is the degree of h(x)?
3
4
5
6
