If (G(t)=82-9t), what is (G(0))?

Advertisement

Answer and explanation

Correct answer: 82

Substituting t=0 gives G(0)=82-9(0)=82. Hence, the initial value is 82. The value 73 is obtained when t=1, so it is not correct here. Exam tip: To find the initial value of a linear function, substitute 0 for the independent variable.
