Solution
- The transformation for reflection over the y-axis is given below:

- We have been given the coordinate of B to be (-5, -2) as shown below:
- Thus, applying the transformation formula given above, we have:

- Thus, the reflected point B' is

- This is shown below:
Answer:
19.135
Step-by-step explanation:
Triangle = 1/2 b h
1/2 x 8.9 x 4.3 = 19.135
First graph: h(x) is decreasing but in [1, too) , is rising
D(x) is decreasing
