Question

Suppose that y = f (x) is an even function and that (3, -4) is a point on the graph of f. Which of the given points is also on the graph of f (x)?
(-3,4)
(-4,3)
(-3,-4)
(4,-3)
(3,4)

Answer 1

for even functions f(x) = f(-x)

Answer 2

so f(3) = f(-3)

Answer 3

f(3) is what in this case?

Answer 4

thanks, i think that's right
