You find the x coordinates using x = -b/2a = -6/2(-1) = 3
Substitute 3 in the equation and find y
y = -(3^2) + 6(3) - 12 = -9 + 18 - 12 = -3
Vertex (3,-3)
B. Multiplying both sides of the equation by 3
Answer:
C
Step-by-step explanation:
The line intersects x-axis at point (-1; 0)
Yes it is also a 50% decrease.
The radius is half the diameter. So the diameter is 14.
