suppose that a function of f has exactly three xintercepts W
suppose that a function of f has exactly three x-intercepts. Which of the following must be true.
A. f is a cubic polynomial function.
B. There are three points on the graph of f which have x-coordinates of 0.
C. The equation f (x) = 0 has exactly three real-number solutions.
D. f is an invertible function.
Solution
Given that function of f has exactly three x-intercepts
A. f is a cubic polynomial function. is a false statement since we didnt know the multiplicity of zeroes
the above statement is true iff each zero if of multiplicity 1
B. There are three points on the graph of f which have x-coordinates of 0 is a true statement
C. The equation f (x) = 0 has exactly three real-number solutions is also true statement
