Plllsss how does adding a positive constant, k, to the input of a rational function affect its axis of symmetry?

a) the axis of symmetry shifts to the left k units

b) the axis of symmetry shifts to the right l units

c) the axis of symmetry doesn’t change

d) the function is no longer symmetric

Step-by-step explanation:

a) the axis of symmetry shifts to the left k units,

Example:  f(x) = 1/x

If we add a positive constant to the input x, as in g(x) = 1/(x+k), the graph of the function translates k units to the left.

step-by-2step explanation:

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
