<prompt> Tloo ka mohlala oa parabola eo axis ea symmetry e leng mola x 4nan  <response>: Instruction in English: Come up with an example of a parabola whose axis of symmetry is the line x 4 . Response in English: One example of a parabola whose axis of symmetry is the line x 4 is the function fx x - 42. In vertex form, this function is written as fx ax - h2 k, where h, k represents the vertex of the parabola, and a determines the direction and the width of the parabola. Since the vertex of this parabola is 4, 0, the axis of symmetry is x h, which is x 4 in this example. . Response in Sesotho: Mohlala o mong oa parabola eo ntlha ea eona ea symmetry e leng mola x 4 e leng mosebetsi fx x - 42. Ka sebopeho sa vertex, mosebetsi ona o ngotsoe e le fx ax - h2 k, moo h, k e emelang vertex ea parabola, me a e lekanyetsa tataiso le bophara ba parabola. . Kaha vertex ea parabola ena ke 4, 0, axis ea symmetry ke x h, e leng x 4 mohlaleng ona.
