One of the transformations used is to shift up 3 units
Given the parent function f(x) = x^2
Given that transformation is applied to the parent function to gt the function g(x)=2x^2−28x+3
You can see from the function that 3 was added as a constant. Hence one of the transformations used is to shift up 3 units
