Linear Transformations
1. Given the graph of \(f(x)=\sqrt x \). Describe the
transformations that occur in the following graphs of \(g(x)\).
solution
(a) \(g(x) = \sqrt{x} + 2 \) (b)
\(g(x) = \sqrt{x+2} -1 \) (c) \(g(x) = -\sqrt{x}
+5 \) (d) \(g(x) = \sqrt{-x} + 3 \)
2. Given the graph of \(f(x)=|x| \). Describe the
transformations that occur in the following graphs of \(g(x)\).
solution
(a) \(g(x) = |x-2| \)
(b) \(g(x) = |x+3| + 5 \) (c) \(g(x)
= |x-1| - 2 \)
(d) \(g(x) = - |x+2| + 3 \)
3. If the graph of \(\displaystyle{f(x) = x^2}\) is shifted 3
units to the right and 2 units down, what is the equation of the new
graph? solution
4. If the graph of \(\displaystyle{f(x) = \sqrt x}\) is shifted 5
units to the left and 4 units up, what is the equation of the new graph?
