What is the direct variation equation for the table of ordered pairs

x y
4 4.8
8 9.6
11 13.2

Y = kx
4.8 = 4k
k = 4.8/4 = 1.2

Therefore, required equation = y = 1.2x

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
