Question

Find f(1) and f(5)?

Answer 1

Hello and Good Morning/Afternoon:

Let's take this problem step by step

First part (a)

• Find f(1)

           $\hookrightarrow \text{which is found by plugging '1' into t's position}\\ f(1)=24(1)^2-93(1) +78=24-93+78\\f(1)=9$

• Find f(5)

           $\hookrightarrow \text{ which is found by plugging '5' into t's position}\\f(5) = 24(5)^2-93(5) + 78 = 24*25-93*5+78 \\f(5)=213$

Second part (b)      

$\hookrightarrow \text {By comparing the calculated data in part (a) to the actual data in part (b)}\\\hookrightarrow \text{We can note that the actual data matches more closely with the calculated data}\\\hookrightarrow \text{ in later years}\\\hookrightarrow \text{ Thus the model is more accurate in later years}$

Answer:

• (a) f(1) = 9 , f(5) = 213
• (b) The model is more accurate in later years

Hope that helps!
