Question

Given the system below:

Answer 1

Answer:

For $f(x)=g(x)$ we can take any value of x =0,1,2,3 etc

Step-by-step explanation:

Given the system

f(x)=$2x$

And g(x)=$2x$

We have  f(x)= g(x)=$2x$

Therferore , the graph of two function is coincident line .

The solutions from graph of two  functions are infinite because both functions are the same .

Therefore, the value of both functions  are same at every value of x.

Therefore, we can choose more tha one value of x.

For examaple, at x=0

f(x)=0 and g(x)=0

At x=1 we get

f(x)=2

And g(x)=2

At x=3 we get

f(x) =$3\times2=6$

g(x)=$3\times2=6$

Therefore , we can see at every value of x the value of two functions are same.

Therefore, we can take x=0,1,2,3,4

Answer 2

If F(x) =g(x) =2x,
x can be any value
