From the text of the task we can write the equation:


3 x^{2} =2(x+4)\\
\\
3x^2=2x+8\\
\\
3x^2-2x-8=0\\
\\
\Delta=(-2)^2-4.3.(-8)=4+96=100\\
\\
x=\frac{2 \pm\sqrt{100}}{2.3}=\frac{2 \pm10}{6}\\
\\
x_1=\frac{2-10}{6}=-\frac{8}{6}=-\frac{4}{3}\\
\\
x_2=\frac{2+10}{2.3}=\frac{12}{6}=2

Write a function g whose graph represents the indicated transformation of the graph of f(x)=x+2; translation 2 units right
miss Akunina [59]

The  function g whose graph represents the indicated transformation of the graph of f(x)=x+2; translation 2 units right is g(x) = x

<h3>Translation of functions</h3>

Translation is a technique used to change the position of an image on an xy-plane. Given the function below;

f(x) = x +2

If the expression is translation 2 units to the right, the translation rule will be:

g(x) = f(x )- 2

Substitute

g(x) = x + 2 - 2

g(x) = x

Hence the  function g whose graph represents the indicated transformation of the graph of f(x)=x+2; translation 2 units right is g(x) = x
