Answer:
2
Step-by-step explanation:
From the graph, we obtain the trigonometric function as:
The corresponding cosine function have equation.
This function is of the form: 
where 
is the amplitude.
Therefore the amplitude is |2|=2
The third choice is correct
Answer: B
Step-by-step explanation: a trapezoid on a coordinate plane that is translated 4 units to the left and 6 units up
The answer is: parent function
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)
