Persamaan fungsi kuadrat pada gambar grafik berikut adalah ...

y=49x2249x+5y=\frac{4}{9}x^2-\frac{24}{9}x+5

y=49x2+249x+5y=\frac{4}{9}x^2+\frac{24}{9}x+5

y=49x2249x5y=\frac{4}{9}x^2-\frac{24}{9}x-5

y=94x2272x+134y=\frac{9}{4}x^2-\frac{27}{2}x+\frac{13}{4}

y=94x2+272x+134y=\frac{9}{4}x^2+\frac{27}{2}x+\frac{13}{4}
