Question

F(x)=5x+6 what is the domain and range

Answer 1

$\mathrm{Domain\:of\:}\:5x+6\:$  

$\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:\ \textless \ x\ \textless \ \infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}$ 

$\text{The function has no points nor domain constraints. So, the domain is}$

$\mathrm{Solution:}\:&\:-\infty \:\ \textless \ x\ \textless \ \infty \\ \:$ 

$\mathrm{Range\:of\:}5x+6$  

$\begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:\ \textless \ f\left(x\right)\ \textless \ \infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}$ 

$\mathrm{The\:set\:of\:values\:of\:the\:dependent\:variable = meaning}$ 

$\mathrm{The\:range\:of\:polynomials\:with\:odd\:degree\:is\:all\:the\:real\:numbers}$ 

$\mathrm{Solution:}\:&\:-\infty \:\ \textless \ f\left(x\right)\ \textless \ \infty$
