(c) f(x) = g(x) for all x, (d) all of above
Answer:

please help me ​

Answer 1

Answer:

c)

Step-by-step explanation:

(c) f(x) = g(x) for all x

Answer 2

Answer:

The correct answer is option (d) all of the above.

Step-by-step explanation:

Given: $f,g$ are two functions.

To find: The objective is to show that the given functions are equal.

We define a function from a set $A$ to a set $B$ as an assignment or rule $f$such that for each $a$∈$A$, there is a unique $b$∈$B$ and $f(a)=b$. Set $A$ is referred to as the domain of $f,$ whereas the set $b$∈$B$ is referred to as the co-domain. If two functions $f$ and $g$ have the same domain and co-domain, and $f(a)=g(a)$ for every $a$ in the domain, we say that the functions are equal.
