Question

Transform y = f(x) by reflecting it across the x-axis. Label the newfunction h(x). Compare the coordinates of the corresponding pointsthat make up the two functions. Which coordinate changes, x ory?

Answer 1

y = f(x)

Reflection, change the sign of the function

y = - f(x)

f(x) -f(x)

1 -1

2 -2

3 -3

8 -8

20 -20

The x coordinate will change.
