X - intercept are: $$ \begin{aligned} & \color{blue}{ x_1 = -1 } \\[1 em] & \color{blue}{ x_2 = 3 } \end{aligned} $$ To find the x-intercepts, we need to solve equation $ x^2-2x-3 = 0 $. (use the quadratic equation solver to view a detailed explanation of how to solve the equation) Step 2:

Step 1) Find the vertex (the vertex is the either the highest or lowest point on the graph). Also, the vertex is at the axis of symmetry of the parabola (ie it divides it in two). Step 2) Once you have the vertex, find two points on the left side of the axis of symmetry (the line that vertically runs through the …

Find the area enclosed by the curve y = x^2-2x-2 and the lines y=1 and x=5 [closed]

2016年2月8日 · y = x2 − 2x −3 is a quadratic equation in standard form, ax +bx +c, where a = 1,b = −2,c = −3. The graph of a quadratic equation is a parabola. You need the axis of symmetry, the vertex, and the x-intercepts. The axis of symmetry is an imaginary line dividing the parabola into two equal halves. The formula for the axis of symmetry is x = −b 2a.
