The graph of the function f(x) = –(x + 3)(x – 1) which statement about the function is true
1.the function is positive for all real values of x where x < –1.
2. the function is negative for all real values of x where x < –3 and where x > 1.
3. the function is positive for all real values of x where x > 0.
4. the function is negative for all real values of x where x < –3 or x > –1.

What are the domain and range of the functiony = 2(x - 3)2 + 4?

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.
