If (g(x)=60-4x), what is the value of (g(3)+g(8))?
Advertisement
Answer and explanation
Correct answer: 76
Given \(g(x)=60-4x\), \(g(3)=60-4\times3=48\) and \(g(8)=60-4\times8=28\). Therefore, \(g(3)+g(8)=48+28=76\). Option 80 can result from an error in multiplication or subtraction. Exam tip: substitute each input into the function separately before adding the results.
