Explain how the setting changes the first time Eric falls asleep. Describe how this change aff the series of events that follows. Use at least two details from the text in your response.

\( \left\{\begin{array}{l}\left.\{6)^{3}\right\}^{2}[(3 x-2)(3 x+2)]^{2}=a x^{4}+b x^{2}+c \\ \text { แล้ว } a+b-c \text { มีค่าเท่ากับข้อใด } \\ \begin{array}{llll}\text { ก. }-7 & \text { ข. }-4 & \text { ค. } 1 & \text { ง. } 9\end{array}\end{array}\right. \)

Let \( f(x)=\frac{14 x^{4}+a x^{2}+b}{7 x^{4}+c x^{2}+d} \), where \( a, b, c \), and \( d \) are unknown constants. Which of the following is a possible graph of \( y=f(x) \) ? Dashed lines indicate asymptotes.

\( \frac{62222\frac{}{}}{} \)

\( \left\{\begin{array}{l}\left\{5 x^{5} \text { ถ้า } 4 x^{4}+28 x^{2}+49=\left(a x^{2}+b\right)\right. \\ \text { แล้ว } a+b \text { มีค่าเท่ากับข้อใด } \\ \text { ก. } 6 \text { ข. } 7 \text { ค. } 8\end{array}\right. \)
