What is the solution to x 3 + 4x 2 > x + 4? –4 1

x < –4 or –1 < x < 1

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

there are no multiple choices
