SOMEBODY HELP!! Do you see any areas in your points that could be considered clusters or outliers? Explain your answer in comple

Yes, the point near 10 is an outlier because it is a variable far away from the others, it may effect your answer (if needed).

Which is the graph of f(x) = (x - 1)(x + 4)?

zheka24 [161]

You can determine this by finding zeros of quadratic function,

$(x-1)(x+4)=0\implies x_1=1, x_2=-4$ .

Which eliminates first and third option.

Now we have up and down parabolas left.

If we factor $(x-1)(x+4)=x^2+4x+\dots$ we find that the coefficient before $x^2$ determines how it is turned, since its positive its an upward turned parabola hence the answer is the last graph.

Hope this helps.

For the polynomial function ƒ(x) = x4 −25x2, find the zeros. Then determine the multiplicity at each zero and state whether the

Veronika [31]

<u>ANSWER</u>

The zeros are $x=-5,x=0,x=5$

EXPLANATION

Given;

$f(x)=x^4-25x^2$ .

We can rewrite the function as

$f(x)=x^2(x^2-25)$

$\Rightarrow f(x)=x^2(x^2-5^2)$

$\Rightarrow f(x)=x^2(x-5)(x+5)$

The zeros are found by equating the function to zero.

$\Rightarrow x^2(x-5)(x+5)=0$

$\Rightarrow (x-5)=0$

The multiplicity is 1, since it is odd the graph crosses at this intercept. which is $x=5$

Or

$\Rightarrow (x+5)=0$

The multiplicity is 1, since it is odd the graph crosses at this intercept. which is $x=-5$

Or

$\Rightarrow x^2=0$

This last root has a multiplicity of 2.

That is

$x=0$ repeats two times.

Since the multiplicity is even, the graph touches the x-axis at the point $x=0$ .

See graph.
