Final answer:
An exponential function can be represented by the equation y = ab^x, where a is the initial value and b is the base. To find the equation that passes through the point (2, 80), we can substitute the values and solve. Additional information is needed to determine the specific equation.
Step-by-step explanation:
An exponential function that passes through the point (2, 80) can be represented by the equation y = ab^x, where a is the initial value and b is the base. To find the specific equation, we can substitute the given point into the equation. In this case, we have 80 = ab^2. With this information, we need another point or the value of either a or b to determine the exact equation.
