When graphing a sine curve model using the equation y = sin bx, the period (or wavelength) will be represented by 7
2x
period
Determine the equation for the sine curve that models the E wave if the
wavelength of E= 1.042 meters.

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 *_*
