1. Diketahui fungsi \( y=9 x^{2}-30 x+26 \) - Tentukan sumbu simestrisnya - Tentukan nilai ekstrimnya dan jenisnya - Tentukan titik puncak kurva - Buatlah grafiknya

Solve the quadratic equations below. (a) \( x^{2}-27=0 \)

Rationalize the Denominator: \( \frac{7+\sqrt{5}}{2+\sqrt{5}} \)

1.) \( \frac{x^{3}-3 x^{2}-4 x+12}{x-3} \) 2.) \( \frac{x^{3}-2 x^{2}+7 x-1}{x^{2}+2} \)

Solve the system by graphing each equation and finding the point of intersection. \( \begin{array}{l}y=\frac{-12}{x+4}+3 \\ y-14=(x+6)^{2} \\ x= \\ y=\end{array} \)

Linear Application The function \( E(t)=3848-77.1 t \) gives the surface elevation (in feet above sea level) of Lake Powell \( t \) years after 1999. Interpret the Slope in this situation. The surface elevation of Lake Powell is Select an answer \( \vee \) at a rate of
