Graph each function. Give the domain and range. ƒ(x) = (1/3)^-x+1

Graph y= 2^x and x = 2^y in the same rectangular coordinate system.

Graph each function. Give the domain and range. ƒ(x) = (1/3)^x+2 - 1

Solve each equation. 4^x-2 = 2^3x+3

Solve each equation. (√2)^x+4 = 4^x

Concept Check. If ƒ(x) = a^x and ƒ(3) = 27, determine each function value. ƒ(-1)

The graph of an exponential function is given. Select the function for each graph from the following options: f(x) = 4^x, g(x) = 4^-x, h(x) = -4^-x, r(x) = -4^-x+3

In Exercises 5–9, graph f and g in the same rectangular coordinate system. Use transformations of the graph of f to obtain the graph of g. Graph and give equations of all asymptotes. Use the graphs to determine each function's domain and range. f(x) = e^x and g(x) = 2e^x/2
