WebThe value of f when applied to x is the image of x under f. y is alternatively known as the output of f for argument x. Now Y=2 is a constant function. The image of Y is always 2 for any value of x. So the Image of function Y=2 is the set containing element 2. Image of 2, under Y=2x−6, is the set containing the element 2 (2)-6=4-6=-2.
