This is the quadratic y=-4x^2+4x+3.
I know that the increase and the decrease of a graph has to do with the y value.
From this, I know that from negative infinity to 0.5, the function is increasing. From 0.5 to positive infinity the graph is decreasing.
In interval notation Increase: (-infinity, 0.5) Decrease: (0.5, infinity) I was wondering if the bracket on the 0.5 is a square bracket or parentheses.
