Select the correct answer. if the zeros of a quadratic function are 3 and 8, what are the factors of the function? a. (x + 8) and (x − 3) b. (x − 8) and (x + 3) c. (x + 8) and (x + 3) d. (x − 8) and (x − 3)

C. (x-8) and (x-3)

Step-by-step explanation:

When we calculate the zeros of a function, we are calculating the points where that function crosses the x axis, and to do so we have to equal the function to zero and isolate X.

The only way a multiplication can have a result of 0, is that any of it's factors were equal to zero. So we can take both factors and equal them to zero and isolate x to know the function's zeros.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

answer is because 4×10=40

and 98×4= is 392
