Preveď všobecný tvar funkcií na vrcholový:
\( \normalsize y=8x^2-16x-7 \)
\( \large y=8(x\ –\frac{16}{2\ \cdot\ 8})^2+(-\ 7-\frac{16^2}{8}) \)
\( \normalsize y=8(x\ –1)^2+(-\ 7-\ 32) \)
\( \normalsize y=8\left(x-1\right)^2-39 \)
\( \large y=8(x\ –\frac{16}{2\ \cdot\ 8})^2+(-\ 7-\frac{16^2}{2\ \cdot\ 8}) \)
\( \normalsize y=8(x\ –1)^2+(-\ 7-\ 4) \)
\( \normalsize y=8\left(x-1\right)^2-11 \)
\( \large y=8(x\ –\frac{16}{2\ \cdot\ 8})^2+(-\ 7-\frac{16^2}{4\ \cdot\ 8}) \)
\( \normalsize y=8(x\ –1)^2+(-\ 7-\ 8) \)
\( \normalsize y=8\left(x-1\right)^2-15 \)
\( \large y=8(x\ –\frac{16}{2\ \cdot\ 8})^2+(-\ 7+\frac{16^2}{4\ \cdot\ 8}) \)
\( \normalsize y=8(x\ –1)^2+(-\ 7+\ 8) \)
\( \normalsize y=8\left(x-1\right)^2+1 \)
