What is the y-intercept of the quadratic function f(x) = (x – 8)(x + 3)? (8,0) (0,3) (0,–24) (–5,0)

For this case we have the following function:
 
 The intersection with the y axis occurs when x = 0
 Therefore, evaluating x = 0 in the function we have:
 
 Then, rewriting the function we have:
 
 Therefore, the intersection with the y axis occurs for the following point:
 
 
 the y-intercept of the quadratic function f (x) = (x - 8) (x + 3) is:
 

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 *_*
