# C1 Mixed Exercise 2G Question 1b watch

1. http://pmt.physicsandmathstutor.com/...hapter%202.pdf
Page 76. How would you know the line of symmetry is at x = 3/4 by simply drawing the graph? I would assume it would be x = 1 because that is the x value in my table of values with the lowest y value at y = -5. So you would assume that the minimum point is x = 1, so the line of symettery would be at x = 1.

Don't do it from the graph and 'table of values'.

At this level you should very well be able to complete the square on and read off the exact line of symmetry from that form.

Yep that makes sense. Thank you. The question in the exercise and solutionbank answer are both misleading.
