To achieve a vertical shrink of the function \( f(x) = 2x + 6 \) by a factor of \( \frac{1}{2} \), you simply multiply the entire function by \( \frac{1}{2} \). This means your new function will be \( g(x) = \frac{1}{2} (2x + 6) = x + 3 \). The result is a function that looks a bit "squished" vertically, but it retains the same slope and y-intercept shifted down. In practical terms, understanding vertical transformations can help in graphing techniques. If you visualize the original line and compare it to the new line, you'll notice it appears less steep—making it easier to analyze relationships in real-world situations like modeling costs or distances. You can apply similar transformations to other equations to fit them into your analysis more conveniently!
