    Answer:

     (7, 0), (-3, 0)

    Step-by-step explanation:

    The x-intercepts are the values of x that make the factors zero. A zero factor makes the value of the function be zero.

      x – 7 = 0   ⇒   x = 7

      x + 3 = 0   ⇒   x = -3

    The corresponding (x, y) coordinates are …

      (7, 0), (-3, 0)
