The vertices of ABC are A(-4,5), B (-2,4), and C(-5,3) if triangle ABC is reflected across the line y=-1 to produce the image A'B'C' find the coordinates of the vertex B'

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"

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 *_*
