Mathematics
1 answer:
nika2105 [10]3 years ago
3 0

Answer:

An even function is:

f(x) = 7

Step-by-step explanation:

An even function accomplish the following condition:

f(x)=f(-x) (1)

Applying (1), we have:

  • f(x)= (x-1)^2 \neq f(-x) \neq (-x-1)^2
  • f(x)= 8x \neq f(-x) \neq -8x
  • f(x)= x^2 -x \neq  f(-x) \neq (-x)^2 +x
  • f(x)=7 = f(-x)= 7

The last one is even.
