Which function does this graph correspond to?
tiny-mole [99]
ANSWER

The function that the given graph corresponds to is
f(x) = (x - 2)(x - 1)(x + 1)(x  + 2)



EXPLANATION

The given graph in the attachment has x-intercepts at

x =  - 2 ,x=-1,x=1  \:  \: and   \: \: x=2


These are the solutions of the polynomial function represented by the given graph.




We can write all these solutions as factors to obtain,

x  + 2  ,x + 1 ,x - 1   \:  \:and \:  \: x - 2


The product of all these factors gives us the function whose graph was drawn.


This implies that,

f(x) = (x - 2)(x - 1)(x + 1)(x  + 2)


Therefore the correct answer is option C.
