If \(f(x)=|x+5|\), what is the value of \(f(-8)\)?

Answer and explanation

Correct answer: 3

Substituting \(x=-8\) in the function gives \(f(-8)=|-8+5|=|-3|=3\). Therefore, the correct answer is 3. Option B is incorrect because the modulus of a number cannot be negative. Exam tip: substitute the given value first, then evaluate the modulus as a non-negative quantity.
