# What are the approximate solution(s) to the given equations, f(x)=6x^2 and g(x)=x+12?

There is no approximate solution to either of these without giving a value to $x$.
For example, $f \left(2\right) = {\left(6 \cdot 2\right)}^{2} = 144$, but $f \left(50\right) = {\left(6 \cdot 50\right)}^{2} = 90000$
The same goes for $g \left(x\right)$, where $g \left(x\right)$ is always $12$ units greater than whatever $x$ is.
