Use the table to answer the question.
x f(x)
−2
1
−1
−2
0 −3
1 ?
If f(x)
is an even function, what is the value of the missing entry in the table?
(1 point)
If f(x)
is even, the missing entry is
-3.
An even function is symmetric with respect to the y-axis. This means that if (x, y) is a point on the graph of f(x), then (-x, y) is also a point on the graph.
From the given table, we can see that f(-2) = -3 and f(2) = -3. Since f(x) is even, the missing entry for f(1) should be the same as f(-1), which is -3.
