The graph of the relation between x and y is as shown in attached figure
By applying the vertical line test we find that the relation is not a function because there are two points which are (1,-1) , (1,3) have the same value of x with different values of y which contradicts with with the rule of function.
X^3 -2x^2 -35x
=x(x^2-2x-35)
=x(x-7)(x+5)
