Answer:
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.
