The options 2 and 4 would have the same graphical representation.
Step-by-step explanation:
Step 1:
To determine which functions are equal to the question, we must assign values to x and see which values equal the function f(x) = .
Any random value can be assigned to x but the same value of x must be assigned to all the equations.
Step 2:
If we substitute x = 5, we get
Question; f(x) =
Option 1; f(x)
Option 2; f(x) =
Option 3; f(x) =
Option 4; f(x)
So options 2 and 4 would have the same graphical representation.
