The degree of the polynomial function f(x) is 4. the roots of the equation f(x)=0 are −6 , −2 , 1, and 3. which graph could be the graph of f(x) ?  

option B

Step-by-step explanation:

The degree of the polynomial function f(x) is 4.

The roots of the equation f(x)=0 are and 3.

We are given with four roots. they are the x intercepts

x intercepts are and 3

The polynomial has degree 4, the polynomial goes up on both sides

We look at the graph that has x intercepts and 3 and both ends of the graph goes up

option B is correct

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
