Answer:
Step-by-step explanation:
Zeros: Set g(r) = (r + 14)^2 - 49 = to 0, obtaining
(r + 14)^2 = 49
Taking the square root of both sides, we get:
r + 14 = ± 7, which results in:
r = -14 + 7 = -7 and r = -14 - 7 = -21
The smaller root is -21 and the larger one is -7.
Vertex: Compare g(r) = (r + 14)^2 - 49 to y = (x - h)^2 + k, where (h, k) represents the vertex. We see that h = -21 and k = -49, so that we know the vertex to be (-21, -49).
