If (F(t)=26+rt) and (F(4)=58), what is (F(9))?

Answer and explanation

Correct answer: 98

Given \(F(t)=26+rt\) and \(F(4)=58\), we get \(26+4r=58\). Thus, \(4r=32\) and \(r=8\). Now \(F(9)=26+8\times9=26+72=98\). Therefore, 98 is the correct option. A value such as 90 can result from an error while finding \(r\) or calculating \(9r\). Exam tip: first substitute the given function value to find the unknown coefficient, then evaluate the required value.
