If f(x) is a even function and (6,8) is one the points on the graph of f(x), what explains why (-6,8) must also be a point on the graph?

Symmetry about y-axis

Step-by-step explanation:

If f(x) is a even function and (6,8) is one the points on the graph of f(x).

Even Function: It makes symmetry about y-axis. The value of y is same from origin to left side and right side of y-axis.

Even function:

For even function, if (6,8) point on f(x) then (-6,8) must be on f(x).

The value of y=8 is same 6 unit from left and right of y-axis 6.

Both points are on function because it is symmetry about y-axis for even function.
