Answer 1

The graph corresponds to the function f(x) = (x + 3)(x + 7) as option A.

Step-by-step explanation:

The graph corresponds to the function f(x) = (x + 3)(x + 7) as option A. In this function, the graph intersects the y-axis at the point (0, 21) and has roots at x = -3 and x = -7. The graph opens upwards and has a positive slope that is decreasing with increasing x.
