Find f(-5) of f (x) = x + 1 1) 4 2) 5 6) 6

F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4

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 *_*

All you have to do is multiply
