Write an exponential function to model the following situation. A population of \( 130,000 \) grows \( 3 \% \) per year for \( 15 \) years. How much will the popluation be after \( 15 \) years? Write an exponential function in terms of \( x \) . \( y = \square ( \square ) ^ { x } \) After \( 15 \) years, the population will be ___(Round to the nearest whole number as needed.)
