If the function \(f(x)=x+1\) has domain \(\{0,2,4\}\), what is its range?

Answer and explanation

Correct answer: \(\{1,3,5\}\)

To find the range, substitute each domain value into the function: \(f(0)=1\), \(f(2)=3\), and \(f(4)=5\). Therefore, the range is \(\{1,3,5\}\). Option B merely repeats the domain, not the range. Exam tip: calculate the function value for every given input to obtain the range.
