Ok so I need help finding out how you write cubic expressions just from looking at the graph.
The problem is that it's a strange cubic that cuts through the y-axis at 6.
I'm not sure how to ask this question but all I can give you is the answer of the graph in it's expression.
So the curve it shows in the paper starts from the point 6 on the y-axis and then comes down to 2 on the x-axis where it touches the x-axis and then goes up and down again through 5 at the x-axis.
The only thing that boggles me is the 0.3, the one number that acts on the whole equation causing it to cut through the y-axis at 6.
It also states that the length of the object is 6m
That's the most detail I can provide into this question. Help would be awesome, thank you.
has -intercepts at 2 and 5.From the graph, write the equation of the cubic.Code:| 6 o | |* * | * * * | * * * ----+-------o----------o---- | 2 5 |
. . Then and are factors of
Since the graph is tangent to the -axis at
. . the factor is raised to an even power.
So, the function has the form: . .
Since is on the graph, we have: .
Substitute into : .
. . Hence: .
