Answer :
The transformations are that the graph is stretched by a vertical factor of 2 and is moved 7 units up.
We are given the functions as:
f(x) = x²
g(x) = 2x² - 7
We need to describe the transformations from f(x) to g(x).
g(x) can be written as:
g(x) + 7 = 2x²
Since x is multiplied with 2, we can say that:
Transformation is: Stretch by a vertical factor of 2.
Since, y coordinate change by 7,
Transformation is: graph is moved 7 units up.
Therefore, we get that the transformations are that the graph is stretched by a vertical factor of 2 and is moved 7 units up.
