Graphing Exponential Functions: Key Concepts and Techniques

What is the general form of an exponential function?

• y = mx + b

• y = a * b^x

• y = a/x

• y = ax^2 + bx + c

In an exponential function, what does the variable 'a' represent?

• The rate of change

• The initial value

• The asymptote

• The exponent
