What kind of transformation converts the graph of f(x)=5|x–7|–9 into the graph of g(x)=5|x–3|?
Question
What kind of transformation converts the graph of f(x)=5|x–7|–9 into the graph of g(x)=5|x–3|?
Solution
The transformation that converts the graph of f(x)=5|x–7|–9 into the graph of g(x)=5|x–3| is a horizontal shift to the right by 4 units.
Here's the step-by-step explanation:
-
The function f(x)=5|x–7|–9 is an absolute value function. The graph of this function is a V-shaped graph that opens upwards. The vertex of this graph is at (7, -9).
-
The function g(x)=5|x–3| is also an absolute value function. The graph of this function is also a V-shaped graph that opens upwards. The vertex of this graph is at (3, 0).
-
Comparing the two functions, we can see that the only difference is in the value inside the absolute value function. In f(x), it's |x-7|, while in g(x), it's |x-3|.
-
This means that the graph of f(x) has been shifted to the right by 4 units to get the graph of g(x). This is because the value inside the absolute value function determines the x-coordinate of the vertex of the graph.
So, the transformation is a horizontal shift to the right by 4 units.
