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.
12 it's adds ×÷2 ( 8÷2=4) and then add the two numbers (8&4)
Divide $55.65 by 7 to get the cost of 1 key chain ($7.95). Then multiply the cost of 1 by 12 and get $95.40
The answer is B (3, 9), (1,-5), (3,3)
