Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step

• They should add 19 instead of subtracting 19

• I can not find an error

• Instead of adding 3k they should subtract 3k

The graph of f(x) = x² has been transformed so that the vertex is now (-2, 8), it opens upward, and is now 3 times as steep. What is the new equation?

• f(x) = (x - 2)² - 8

• f(x) = 3(x + 2)² + 8

• f(x) = -3(x + 2)² + 8

• f(x) = 3(x + 2)² - 8
