The Deep Dive
Did you know that both functions \( f(x) = \sqrt{x-3} \) and \( g(x) = \sqrt{x+4} \) represent transformations of the basic square root function? The function \( f(x) \) is shifted 3 units to the right, while \( g(x) \) is shifted 4 units to the left of the origin. This means that while the domain of \( f(x) \) starts at \( x = 3 \) (where the square root becomes valid), \( g(x) \) can accept values as low as \( x = -4 \). You might find it interesting to explore the intersection of these two functions! To do this, set \( f(x) = g(x) \) and solve the equation \( \sqrt{x-3} = \sqrt{x+4} \). Squaring both sides will give you a quadratic equation. Just remember to check for extraneous roots after solving, as squaring can introduce solutions that don't fit in the original context!
