Given:

The function is

[tex]f(x)=x^3-7x^2+10x[/tex]

To find:

The end behavior of its graph.

Solution:

We have,

[tex]f(x)=x^3-7x^2+10x[/tex]

Here, leading coefficient is 1 which is positive and degree of function is 3 which is odd.

For odd degree and positive leading coefficient, the end behavior is

[tex]f(x)\to \infty\text{ as }x\to \infty[/tex]

[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]

Using this, we get

[tex]\text{As }x\to \infty, y\to \infty[/tex]

[tex]\text{As }x\to -\infty, y\to -\infty[/tex]

Therefore, the correct statements are A and D.

We want to study the end behavior of the given polynomial.

The two correct statements are A and D.

  • As x β†’ ∞, y β†’ ∞
  • As x β†’ βˆ’βˆž, y β†’ βˆ’βˆž

The polynomial is:

f(x) Β = x^3 - 7*x^2 + 10*x.

We can see that the degree of this polynomial is odd, this means that the behavior on the negative side is opposite to the one in the positive side.

In this case, the leading coefficient is one, so it is positive. This will mean that, for large positive values of x, f(x) will be positive.

For large (in absolute value) negative values of x, f(x) will be negative.

Then the end behavior is given by:

  • As x β†’ ∞, y β†’ ∞
  • As x β†’ βˆ’βˆž, y β†’ βˆ’βˆž

So the two correct statements are A and D.
