Vertex is (-2,-3) and it's a minimum.
The absolute value of -1/3 is 1/3. I guess by using the number line you move 2(1/3) to the right from the point -1/3
Answer:
x = 7 ± 
Step-by-step explanation:
Given
4(x - 7)² - 48 = 12 ( add 48 to both sides )
4(x - 7)² = 60 ( divide both sides by 4 )
(x - 7)² = 15 ( take the square root of both sides )
x - 7 = ±
( add 7 to both sides )
x = 7 ±
