A function is shown.
f(x) = x² + 2x  1 Which graph represents this function?
In the function f(x) = x² + 2x  1,
 the constant term, 1, is the yintercept of the graph  the x² term is positive, meaning the parabola opens upward  also, the xcoordinate of the vertex is b 2  =  = 1 is the xcoordinate of the vertex 2a 2(1) yintercept is 1 parabola opens up xcoordinate of vertex is 1 Graph C.) {the one on the top right} Ask Algebra House Comments are closed.
