Answer:
<em>x > 2
</em>
<em>x ∈ ( +2 ; + oo )</em>
Step-by-step explanation:
<em>8 - 2x < 4
</em>
<em>8 - 4 < 2x
</em>
<em>4 < 2x | : 2
</em>
<em>2 < x
</em>
<em>
</em>
<em>x > 2
</em>
<em>x ∈ ( +2 ; + oo )</em>

Answer:
4x / (2x^2+1)
Step-by-step explanation:
g(x)=ln(2x^2+1)
Using u substitution
u= 2x^2 +1
du = 4x dx
g'(x) = d/du ( g(u) du)
We know that the derivative of ln(u) = 1/u since this is always positive
= 1/ u* du
Substituting x back into the equation
g'(x) = 1/(2x^2+1) * 4x
= 4x / (2x^2+1)
