Final answer:
In a second-order regression model, the general form is y = a + bx + cx². To find the prediction equation, specific data points and corresponding wage growth values are needed.
Step-by-step explanation:
The general form of a second-order regression model is given by the equation:
y = a + bx + cx²
In this case, the wage growth is the dependent variable (y), and x represents the independent variable (such as years). The general form of the second-order regression model for wage growth would be:
wage growth = a + bx + cx²
To find the prediction equation, we need specific data points and the corresponding values for wage growth.
