Answer:
see attached graph
Step-by-step explanation:
Given equation:
Standard form of a quadratic equation:
where is the y-intercept
If then the parabola opens upwards.
If then the parabola opens downwards.
Therefore, the y-intercept of the graph is (0, 3)
To find the x-intercepts, factor the equation:
Therefore, the x-intercepts of the graph are (3, 0) and (1, 0)
To determine the vertex, differentiate the equation:
Set to zero and solve for x:
Substitute into the original equation and solve for y:
Therefore, the vertex (or turning point) is at (2, -1)
