Histology (compound of the Greek words: á¼±ÏÏÏÏ histos tissue, and - Î»Î¿Î³Î¯Î± -logia science) is the study of the microscopic anatomy of cells and tissues of plants and animals.
Reflection in the x-axis. A reflection in the x-axis can be seen in the picture below in which A is reflected to its image A'. The general rule for a reflection in the x-axis: (A,B) (A, âB) Reflection in the y-axis. A reflection in the y-axis can be seen in the picture below in which A is reflected to its image A'.
That is what makes them reflections about the y-axis. 4) Reflections about the line y = x is accomplished by interchanging the x and the y-values. Thus for y = f(x) the reflection about the line y = x is accomplished by x = f(y). Thus the reflection about the line y = x for y = x2 is the equation x = y2. These are graphed on the following graph: The blue line is where you would fold the paper for these two graphs to match. Notice that the green parabola is opening up but when you fold it across the blue line, it opens to the right.
