Answer:
B
Step-by-step explanation:
Given
4x² - 72x = 0 ← factor out 4 from each term
4(x² - 18x) = 0
To complete the square
add/subtract (half the coefficient of the x- term)² to x² - 18x
4(x² + 2(- 9)x + 81 - 81) = 0
4(x - 9)² - 4(81) = 0
4(x - 9)² - 324 = 0 ( add 324 to both sides )
4(x - 9)² = 324 ( divide both sides by 4 )
(x - 9)² = 81 ( take the square root of both sides )
x - 9 = ± 
= ± 9 ( add 9 to both sides )
x = 9 ± 9
Then
x = 9 - 9 = 0
x = 9 + 9 = 18
Answer:
the answer is
Step-by-step explanation:
1= A(3, 2) B (1, -1) C(4, -2)
2= A(3, 8) B(1, 5) C(4, 4)
3= A(3, -4) B(1, -7) C(4, -8)
4= A(7, 2) B(5, -1) C(8, -2)
5= A(-1, 2) B(-3, -1) C(0, -2)
Answer:
1. What is the y-intercept? y = 4
2. What is the maximum point? 4
3. What are the x-intercepts? (write the negative one first) x = -2 and x = 2
Step-by-step explanation:
In simple terms, the y-intercept is the part (s) where the graph hits the vertical line.
The maximum point is the highest point of the graph, coincidentally the maximum point on this graph is right on the y-intercept.
In simple terms, the x-intercept is the part (s) where the graph hits the horizontal line.
