Write the point-slope form of a linear equation given the point (-1, 4) and a slope of 3.

3) \( h(x)=-x^{2} \)

4.) จงแยกต้วประกอบของ \( 16 x^{4}-200 x^{2}+625 \)

Compute the difference quotient, \( \frac{f(x+h)-f(x)}{h} \), of the function \( f(x)=9 x^{3} \), and simplify the answer as much as possible. \( \frac{f(x+h)-f(x)}{h}=\square \)

Brianna made an apple pie. She used \( 2 / 3 \) of a tablespoon of cinnamon and \( 1 / 2 \) of a tablespoon of nutmeg. How much more cinnamon than nutmeg did Brianna use? Write your answer as a fraction or as a whole or mixed number. Submit tablespoons

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