Review Lesson 3-5: Solve the system by using an augmented matrix and Desmos' matrix calculator. Take a screenshot of your work at Desmos and upload or paste it to the Formative canvas.
Which matrix represents the rref (reduced row echelon form) of the augmented matrix?
Review Lesson 2-7: Without graphing, match each vertex, axis of symmetry, and transformation from the parent function f(x) = |x| in the left column with the appropriate absolute value function in the right column.
vertex: (2, 0)
axis of symmetry: x = -4
compress the parent function horizontally by a factor of 2 and translate 4 units to the right
translate the parent function 2 units up and 4 units left
vertex: (-4, 2)
axis of symmetry: x = 2
