if f(x) = (x-3)^2 , then f(2) x f(5) belongs to

Answer 1

To find the value of f(2) x f(5), we first need to evaluate f(2) and f(5).

f(x) = (x-3)^2

Now, substituting x = 2:

f(2) = (2-3)^2 = (-1)^2 = 1

Substituting x = 5:

f(5) = (5-3)^2 = (2)^2 = 4

Finally, we can find the value of f(2) x f(5):

f(2) x f(5) = 1 x 4 = 4

Therefore, f(2) x f(5) belongs to the set of real numbers.
