What kind of transformation converts the graph of f(x)=|x|+1 into the graph of g(x)=7|x|+7?
Question
What kind of transformation converts the graph of f(x)=|x|+1 into the graph of g(x)=7|x|+7?
Solution
The transformation that converts the graph of f(x)=|x|+1 into the graph of g(x)=7|x|+7 is a vertical stretch by a factor of 7 and a vertical shift upwards by 6 units.
Here's the step-by-step explanation:
-
Vertical Stretch: The coefficient of |x| in g(x) is 7, which is 7 times the coefficient of |x| in f(x). This means the graph of f(x) is stretched vertically by a factor of 7 to get the graph of g(x).
-
Vertical Shift: The constant term in g(x) is 7, which is 6 more than the constant term in f(x). This means the graph of f(x) is shifted upwards by 6 units to get the graph of g(x).
