Question

let f:xR-{0} to R define by f(x)=1/x^2 for all x belongs to R -{0} find it's domain and range and draw it's graph​

Answer 1

Answer:

Correct option is

B

Doman=R,Range=(−∞,2]

Given f(x)=2−∣x−5∣

Domain of f(x) is defined for all real values of x.

Since, ∣x−5∣≥0⟹−∣x−5∣≤0

⟹2−∣x−5∣≤2⟹f(x)≤2

Hence, range of f(x) is (−∞,2].
