Question

The functions f(x) and g(x) are graphed.

Which represents where f(x) = g(x)?

f(2) = g(2) and f(0) = g(0)
f(2) = g(0) and f(0) = g(4)
f(2) = g(0) and f(4) = g(2)
f(2) = g(4) and f(1) = g(1)

Answer 1

I think the answer is the first one f(2) = g(2) and f(0) = g(0)

Answer 2

First option is correct.

Explanation:

two functions are equal if their domain and co-domain are equal, and if the image of both functions is the same .

here we have two values of x ,2 and 0 at which both f(x) and g(x) gives same

values that is f(2) = g(2) and f(0) and g(0)

therefore x =0 and x=2 are the values at which functions are equal.
