To find the point on the graph described by the function y=(2x+1)^2-4, we need to substitute the x-coordinate into the equation and solve for the y-coordinate.
If we substitute x = 1 into the equation, we get:
y = (2(1) + 1)^2 - 4
y = (2 + 1)^2 - 4
y = (3)^2 - 4
y = 9 - 4
y = 5
Therefore, the point on the graph is (1, 5).
None of the given options match the calculated point (1, 5), so none of the provided points are on the graph.
