Answer:

$x>\frac{1}{2} \\x$

Step-by-step explanation:

If we solve for 'x' variable, its recommended to multiply 'x' variable in both sides of inequality:

we have $\frac{1}{4}< x^{2} \\$

This is a quadratic equation, two answer are going to be obtained from here.

since $\sqrt{x^{2} } = |x|$

Applying square roots to both sides of inequality sign we wil have the following

$\sqrt{\frac{1}{4} } < \sqrt{x^{2} }$

This leaves to the following

$\frac{1}{4}$

remember that $|x|= +/ - x$

$x>\frac{1}{2} \\x$

Given the following functions f(x) and g(x), solve f over g(−4) and select the correct answer below:

marishachu [46]

$\left(\dfrac{f}{g}\right)(x)=\dfrac{f(x)}{g(x)}\\\\f(x)=4x-4;\ g(x)=x-1\\\\f(-4)=4\cdot(-4)-4=-16-4=-20\\\\g(-4)=-4-1=-5\\\\\left(\dfrac{f}{g}\right)(x)=\dfrac{-20}{-4}=4$
