If (F(t)=13+4t), what is (F(0))?
Answer and explanation
Correct answer: 13
Given \(F(t)=13+4t\), substitute \(t=0\): \(F(0)=13+4(0)=13\). Therefore, the correct answer is 13. The number 4 is the rate of growth (the coefficient of \(t\)), not the initial value. Exam tip: In a linear expression \(a+bt\), the value at \(t=0\) is always the constant term \(a\).
