Answer:
D.
Step-by-step explanation:
The point-slope form of a line is given by:
The line given to us has equation; .
The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.
Our slope of interest is therefore;
Since the point goes through (-2,7), we have .
We plug in the slope and the point into the point-slope formula to obain;
The required equation is:
The total number of roots of the given polynomial function is 6.
The given polynomial is .
We need to determine the total number of roots of the given polynomial function.
What is the total number of roots of the polynomial function?
The number of roots of any polynomial is depended on the degree of that polynomial. Suppose n is the degree of a polynomial f(x), then fx) has n number of roots.
Here, the degree of the given polynomial function is 6.
Therefore, the given polynomial function will be having 6 roots.
