F(x)={3x+5when x<−1,-x^2+3when x≥−1}

If f is the function defined above, then f′(−1) is

I’m sorry i can’t u

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 *_*
