According to the rational root theorem, -2/5 is a potential rational root of which function?
a. f(x)=4x^4-7x^2+x+25
b. f(x)=9x^4-7x^2+x+10
c. f(x)=10x^4-7x^2+x+9
d. f(x)=25x^4-7x^2+x+4

x + 4/7

step-by-step explanation:

use cymath

about 0.75 hours

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
