If f(x) is an even function and (6, 8) is one the points on the graph of f(x), which reason explains why (–6, 8) must also be a point on the graph? since the function is even, the outputs of a negative x-value and a positive x-value are the same. since the function is even, the outputs of a negative y-value and a positive y-value are the same. the graph has rotational symmetry, so the point will be reflected across the y-axis. the graph has rotational symmetry, so the point will be rotated 90 degrees about the origin. im in the middle of a test

If is an even function, then . In this case, .

This is because an even function is symmetric about the . Hence the outputs of a negative x-value and a positive x-value are the same.

The correct option is the first option.

Since the graph is even, the outputs of a negative x-value and a positive x-value are the same.

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

no, because the sides are not congruent
