Answer:
Opening: Opens upwards
Axis of Symmetry: -7/2
Vertex: (-7/2, -81/4)
X - intercepts: (1, 0) and (-8, 0)
Y - intercept: (0, -8)
Step-by-step explanation:
Opening: 'a' is greater than zero
Axis of Symmetry:
Vertex:
X - intercepts:
(x-1)(x+8)
x = 1 and x = -8
Y - intercept: (0, -8)
Add 12 to 16 on the other side to make 4x = 28. Then divide 28 by 4, which equals 7. Solution is x = 7
Answer:
7:5 is the same as 21: 15
Step-by-step explanation:
21/7 = 3 and 3*5=15
i divided 21 by 7 to see how many times it was multiplied to get there, so i could do the same thing to the 5
I hope this helps :)
3+7=10
7+3=10
8+2=10
17-7=10
Answer:
g(x) = -x² - 4
Step-by-step explanation:
In this case, we are only changing <em>a </em>(reflection and vertical shrink/stretch) and <em>k </em>(vertical movement)
<em>k </em>= -4 because we are moving 4 units down
<em>a </em>= -1 because we are just reflecting over the x-axis
