Given the function f(x) = √x-8 + 3 which of the following is the value of f(24)
kvasek [131]

Answer:

The answer is 7.

Step-by-step explanation:

You have to substitute the value of x into the function :

f(x) =  \sqrt{x - 8}  + 3

f(24) =  \sqrt{24 - 8}  + 3

f(24) =  \sqrt{16}  + 3

f(24) = 4 + 3

f(24) = 7
