Q6. PrepSwift Quant Tickbox Quiz #9 (Coordinate Geometry Column 3)

[Ami]

what if f(x) = x and f(x+3) will make the graph shift to left by 3 units
so f(x) = x won’t cut the x axis however f(x+3) will cut it once

similarly what if f(x) = x-3 and f(x+3) = x will make the graph shift to to origin;
Not sure of where I am going wrong
Please guide anyone!

@Ami

so f(x) = x won’t cut the x axis

It does intersect with the x axis. (0,0) is a point on f, which is clearly on the x-axis.

Oh ya!! got it
origin lies on both the axis
