(b) What is the amplitude of the function?
(c) What is the midline of the function?
(d) Sketch the first two periods of the graph of the function. Plot and label the key points of the graph. Label each axis with an appropriate scale
Answer:C
Step-by-step explanation:
C=2√A
Where A= area
C=25.13
Answer:
-4
Step-by-step explanation:
The direction of the parabola depends on the sign of the leading coefficient i.e. sign of the coefficient with the squared term.
Remember these two points for vertical parabola:
We are given that the parabola opens down. This means that the leading coefficient must be negative. Among the given options only one option contains a negative number i.e. -4.
Therefore, the missing coefficient could be -4
