Question

If f(c)=0, then which is true?
A. the point (0,c) lies on the graph of f(x)
B. the point (-c,0) lies on the graph of f(x)
C.x-c is a factor of f(x)
D.x+x divides evenly into f(x)

Answer 1

well what you have is the fact that when x = c the value of f(x) is zero.

which means that x = c is a zero of the function

which also means (x - c) is a factor.

hope it helps
