Question

- Identify the vertex of y = 8|x - 21 +3.

a. (3,2)
b. (8,-3)
C.
(2,3)
d. (8,2)

Answer 1

Explanation:

the vertex will be (2,3), because the vertex formula is y=a(x-h)+k, then take -h and make positive and k stays the same where it negative positive, but when h is negative = positive, when h is positive=negative, so the answer is C
