For the function y=2x^{2}-4x-6, determine the coordinates of the x- intercept and the y- intercept.

b) determine the equation of the axis of symmetry

c) determine the coordinate of the vertex

e) graph the function and label and indicate an appropriate scale on the axes

Step 1

**First of all, to find the x-intercept put y = 0 in equation (1) and find x.**

**Similarly, to find the parabola’s y-intercept put x = 0 in equation (1) and simplify to get y.**

Therefore, x-intercept is (-1, 0) and (3, 0) and y-intercept is (0, -6).

Step 2

**(b) Now, the symmetry axis is defined as the vertical line or horizontal line which passes through the parabola’s vertex.**

Therefore, the symmetry axis is at x = 1.

Step 3

**(c) The vertex’s x-coordinate is at x = 1. So put the value o...**
