Can someone explain to me how this problem is completed and graphed as well as how to find the x, y intercept and their vertex coordinates and the axis of symmetry
f(x) = x2 + 2x - 3

x - intercept = 1, -3

y - intercept = -3

vertex = (-1, -4)

axis of symmetry is x = -1

Step-by-step explanation:

f(x) = x^2 + 2x - 3

The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis.

x = 1, -3

y = -3

Vertex coordinate is the point where the parabola changes direction. In this case, vertex is (-1, -4)

Axis of symmetry is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

So axis of symmetry is x = -1

To be honest, if you graph the equation on the calculator, it will be easy to find all of these once you understand its definition and what it is.

no, because the sides are not congruent

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
