Problem 24
Describe the equations of the quadratic functions that go through the points (-1,3) and \((2,6) .\) Give 2 examples.
Problem 25
Rewrite the system of equations in matrix form. Find the solution to the linear system by simultaneously manipulating the equations and the matrix. $$ \begin{aligned} -5 x_{1}+\quad 2 x_{3} &=14 \\ x_{2} &=1 \\ -3 x_{1}+\quad x_{3} &=8 \end{aligned} $$
Problem 26
Rewrite the system of equations in matrix form. Find the solution to the linear system by simultaneously manipulating the equations and the matrix. $$ \begin{aligned} -5 x_{2}+2 x_{3} &=-11 \\ x_{1}\quad+2 x_{3} &=15 \\ -3 x_{2}+x_{3} &=-8 \end{aligned} $$
