What happens to a number when it is raised to a negative exponent?

• It becomes zero

• It becomes a fraction

• It becomes negative

• It remains the same

Why can Y never be negative in an exponential function?

• Because the base is always positive

• Because the function is undefined for negative Y

• Because X is always positive

• Because negative exponents make the value positive

What is the first step in solving an exponential equation?

• Graph the function

• Find the base

• Find the exponent

• Plug in the first point

What is the equation of an exponential function that passes through the points (0, 3) and (1, 15)?
