Answer:
g(x) = –5*(0.8)^x
Step-by-step explanation:
In order to get the reflection of a function across the x-axis, you have to multiply that function by (-1)
Given the function:
f(x) = 5*(0.8)^x
then, its reflection across the x-axis is -f(x) = g(x) = –5*(0.8)^x. This result can be checked replacing the known points into the equation, as follows:
x | g(x)
0 | –5*(0.8)^0 = -5
1 | –5*(0.8)^1 = -4
4 | –5*(0.8)^4 = -2
