Question

Consider f(x)=root(x-5)

Find the value of x for which f is undefined


Explain in detail please! I’m pretty stupid so...

Answer 1

Answer:

x < 5

Step-by-step explanation:

f(x) = √(x−5)

f(x) is undefined when the expression under the radical is negative.

x − 5 < 0

x < 5

Therefore, f(x) is undefined when x is less than 5.
