Graph the function y = 2x2 - x - 4x + 5. To the nearest tenth, over which interval is the function decreasing?

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 *_*

The answer would be 7 cages
