Graph the Equation $$\frac { y } { 7 } = \sqrt { 1 + \frac { x ^ { 2 } } { 36 } }$$

Graph the equation. Give the domain and range. Identify whether the equation is a function.
- $$\frac { y } { 7 } = \sqrt { 1 + \frac { x ^ { 2 } } { 36 } }$$

A)

$( \infty , \infty ) ; ( \infty , - 7 ] ;$ not a function

B)

$( \infty , \infty ) ; [ 1 , \infty ) ;$ function

C)

$( \infty , \infty ) ; [ 7 , \infty )$ ; function

D)


$( \infty , \infty ) ; ( \infty , - 1 ]$ ; not a function
