Question 285914: Evaluate the exponential equation for three positive values of x, three negative values of x and at x=0. Transform the second expression into the equivalent logarithmic equation; and evaluate the logarithmic equation for three values of x that are greater than 1, three values of x that are between 0 and 1, and at x=1. Use the resulting ordered pairs to plot the graph of each function.
y=2^-(x-2), x=2^-(y-2).
I do not understand this problem at all.

The first part of the problem says to substitute three + values , 3 - values, and 0 for x
y=2^-(x-2), x=2^-(y-2)
so plug in 3 + values such as 1 2 and 3
three negative values -1 -2 -3
and 0
do that much and we can proceed.
for x=1
y=2^-(x-2)
x=1
y=2^-(1-2)
work it out
x=2^-(y-2)
1=2^-(y-2)
work it out
