\#\#\# 4. Membuat Grafik Untuk menggambar grafik fungsi kuadrat ini, kita dapat menggunakan informasi yang telah kita temukan: - Sumbu simetris: \( x=\frac{5}{3} \) - Titik puncak: \( \left(\frac{5}{3}, 1\right) \) - Nilai \( y \) ketika \( x=0 \) (intersep \( y \) ): \( y=9(0)^{2}-30(0)+26=26 \) - Nilai \( y \) ketika \( x=1: \) \( y=9(1)^{2}-30(1)+26=9-30+26=5 \) - Nilai \( y \) ketika \( x=2: \) \( y=9(2)^{2}-30(2)+26=36-60+26=2 \)

7. \( 2 x^{2}+x-4=0 \) \( \begin{array}{ll}\text { a. }-\frac{1}{2} \pm \frac{\sqrt{33}}{4} & \text { c. }-\frac{1}{4} \pm \frac{\sqrt{33}}{4} \\ \text { b. }-4 \pm \frac{\sqrt{66}}{4} & \text { d. }-\frac{1}{2} \pm \frac{\sqrt{33}}{2}\end{array} \)

1.3 \( a \times a \times a \times a \) canbe expressed as. (a) \( 4 \times a \) (b) \( 4^{a} \) (c) \( 9 / 4 \) (d) \( a^{4} \) 14 The HCF of 40 and 60 . (a) 10 (b) 5 (c) 20 (d) 12

Solve the inequality. Express the solution set in set-builder notation and interval notation. Graph the solution set on a real number line. \[ 5(x-6)>4(x-6)+x \]

Graph the parabola. \[ y=(x-1)^{2}+5 \] Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function button.

Elsa løper ei løype som er \( 1,75 \mathrm{~km} \) kortere enn den William loper, Tariq løper \( 15,95 \mathrm{~km} \), og det er 2,43 lenger enn William. Hvor langt løper Elsa og William?
