Answer:
The vertices of the figure after a reflection across the x axis are (0,-4), (3,-8) and (4,0).
Step-by-step explanation:
A figure has the following vertices:
A(0,4), B(3,8) and C(4,0)
When we reflect across the x-axis, we keep the values of x, while the y-values change the signal. So
A(0,4) -> A'(0,-4)
B(3,8) -> B'(3,-8)
C(4,0) -> C'(4,0)
The vertices of the figure after a reflection across the x axis are (0,-4), (3,-8) and (4,0).
