For x = -3: Y = (-3)^2 - 4(-3) + 3 Y = 9 + 12 + 3 Y = 24 For x = -2: Y = (-2)^2 - 4(-2) + 3 Y = 4 + 8 + 3 Y = 15 For x = -1: Y = (-1)^2 - 4(-1) + 3 Y = 1 + 4 + 3 Y = 8 For x = 0: Y = (0)^2 - 4(0) + 3 Y = 0 + 0 + 3 Y = 3 For x = 1: Y = (1)^2 - 4(1) + 3 Y = 1 - Show more…

2a. The graph of the quadratic function f(x) = 1/2(x - 2)(x + 8) intersects the y-axis at (0, c). Find the value of c. 2b. The vertex of the function is (-3, -12.5). Write down the equation for the axis of symmetry of the graph. 2c. The equation f(x) = 12 has two solutions. The first solution is x = -10. Use the symmetry of the graph to show that the second solution is x = 4. 2d. Write down the x-intercepts of the graph.

Find the $x$ - and $y$ -intercepts (if they exist) and the vertex of the graph. Then sketch the graph using symmetry and a few additional points (scale the axes as needed). Finally, state the domain and range of the relation. $$x=y^{2}-2 y-3$$

The Analytic Parabola
Graph each parabola and give its vertex, axis, $x$ -intercepts, and $y$ -intercept. $f(x)=\frac{1}{3} x^{2}-\frac{8}{3} x+\frac{1}{3}$
