Answer:
Explanation:
The task is to draw the parabola of the equation
on the given graph.
The first step we can take to doing this is to use the table on the left hand side to work out our x and corresponding y-values to use as plotting coordinates. To do this you want to substitute the given value for x which will give you a corresponding y-value.
E.g:
x |
| y
0 |
| -4
Here we have gotten the coordinates (0, -4) so this will be a point on the graph.
Repeat with all other values on the table and you should get a bunch of dots which lead upwards in a curved line from a point. Extend the lines to form a parabola shape (A u-shape).
Once you have drawn the graph, label the parts.
Roots: The places where the line crosses the x-axis
Vertex: The lowest point of the parabola
Line of symmetry: The vertical line in which the parabola reflects/ is the same either side (Has equation x=_).
y-intercept: The point where the line crosses the y-axis.
Hope this helped!
