The statement which is true about the function is that the function is negative for all real values of x where x < –3 or x > –1.
A function assigns the value of each element of one set to the other specific element of another set.
The graph of the function is,
[tex]f(x) = -(x +3)(x - 1)[/tex]
It is positive, its value is above x-axis. For the function above, the solutions are,
[tex]x+3=0\\x=-3\\x-1=0\\x=1[/tex]
The value of x is lies between,
[tex]-3 < x < 1[/tex]
Thus, the statement which is true about the function is that the function is negative for all real values of x where x < –3 or x > –1.
