Evaluate the given exponential equations for three positive values of x, three negative values of x, and at x=0.
y=2^(x+2)
x=4^(y+2)
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, and show the relevant work.
