If (Z(t)=7+11t), what is the growth rate?
Answer and explanation
Correct answer: 11
In the linear expression Z(t)=7+11t, the coefficient of t is 11. For every increase of 1 unit in t, Z increases by 11 units, so the growth rate is 11. The number 7 is the initial value, not the growth rate. Exam tip: In a linear expression of the form at+b, the coefficient of t gives the rate of growth or decay.
