Answer:
Step-by-step explanation:
So a geometric sequence can be explicitly defined as: . IN this case we're given r, but we don't know what a_1 is. We can find this by lugging in 4 as n, and -8 as a_n, since they're given values
Plug known values in:
Subtract the values in the exponent
Simplify the exponent
Divide both sides by -8
So the nth term can be defined as: , and since the 1 is redundant, the equation can simply be defined as:
The graph of y₂ below is the graph of the reflection of f(x) across the x-axis.
