Domain is set of all x-values. You are supposed to focus on the x-axis instead.
From the graph, the point starts from x = -5 and ends on x = 5. That means no values would exist after x = 5 or before x = -5.
Hence, the domain starts from -5 to 5.
Answer
Answer:
(x + 9)² = 36
Step-by-step explanation:
Given
x² + 18x + 57 = 12 ( subtract 57 from both sides )
x² + 18x = - 45
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(9)x + 81 = - 45 + 81
(x + 9)² = 36
Answer:
7 and 9
Step-by-step explanation:
I think 24 might be the answer if not its 15
21 + 20 = 43
Total is 123, so divide by 43.
123/43 = 2.86 rounded to 3.
