Question

Given f(x)=squarerootof(x−3), what is f(12)?

Answer 1

Answer:

± 3

Step-by-step explanation:

Given f(x)=square root of (x−3), what is f(12)?

Given f(x) is equal to square root of (x – 3)

We need to find the value of f(12)  

Given f(x) = √x – 3

We are given the value of x as 12

So f(12) = √12 – 3

So f(12) = √9

Now f(12) = 3

So f(12) = ± 3
