ketch the graph of \( f(x)=2 x^{2}-4 x+7 \)

Solve the system by the addition method. If there is no solution or an infinite number of solutions, so state. Use set \( \left\{\begin{array}{r}2 x-4 y=4 \\ 2 x-4 y=5\end{array}\right. \) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. There is exactly one solution. The solution set is \( \} \). (Simplify your answer. Type an ordered pair, using integers or fractions.) B. There are infinitely many solutions. The solution set is \( \{(x, y) \mid 2 x-4 y=4\} \) or \( \{(x, y) \mid 2 x-4 y=5\} \).

a. \( \left(\frac{2}{3}\right)^{4}= \)

Find \( \frac{d y}{d x} \) given \( y^{2}-x^{2} y+5=17 \)
