The graph shifted by 5 units

Answer:

Option B - The graph shifts 5 units left.

Step-by-step explanation:

Given : Equation 1- \(f(x)=2^{x-2}\)

after replacing the function we get, equation 2-  \(g(x)=2^{x+3}\)

The function  \(f(x)=2^{x-2}\) is transformed to g(x) when we add 5 in the x value

\(f(x)=2^{x-2}\)

⇒ \(f(x+5)=2^{x-2+5}\)

⇒ \(f(x+5)=2^{x+3}=g(x)\)

and when we add something in the x value then the graph shifted to left by that unit.

mathematically we can write,  

f(x)→ f(x+b) →  f(x) shift left with b units

Therefore, the graph shifts 5 unit to the left

Hence, option B is correct
