It is solution c. You substitute ABC for DEF.
Answer:
12, 2, 0, -2 and 8
Step-by-step explanation:
Give the function f(x) = -x+2
If x = -10
y = -(-10)+2
y = 10+2
y = 12
If x = 0
y = -0+2
y = 2
If x = 2
y = -2+2
y = 0
If x = 4
y = -4+2
y = -2
If x = 10
y = -10+2
y = -8
Hence the outputs are 12, 2, 0, -2 and 8

Interesting factoid: Only perfect squares have an odd number of factors. So we know to try 4, 9, and 16, and ignore the rest. It's 16, whose factors are 1, 2, 4, 8, and. 16 .
