The axis of symmetry for a function in the form f(x) = x2 + 4x − 5 is x = −2. what are the coordinates of the vertex of the graph?
Answers: 2
The graph of a quadratic function is called a parabola.
The axis of symmetry is 
, i.e., 
Thus, the statement in the question for the symmetry axis x = -2 is correct.The vertex (or turning point) is 
where 
or 
The parabola opens upward because a > 0, resulting in a vertex that is a minimum.
The factorization of f (x) = x² + 4x - 5 becomes f(x) = (x + 5)(x - 1). Then we get the x-intercepts at

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
