Answer:

To check if a relation is a function, given a mapping diagram of the relation, use the following criterion: If each input has only one line connected to it, then the outputs are a function of the inputs. Example: In the following mapping diagram, y is a function of x, but x is not a function of y: Line Test.

3logbase5(x^2+9)-6=0

Pavlova-9 [17]

$3\log_5(x^2+9)-6=0$
$3\log_5(x^2+9)=6$
$\log_5(x^2+9)=2$
$5^{\log_5(x^2+9)}=5^2$
$x^2+9=25$
$x^2=16$
$x=\pm\sqrt{16}$
$x=\pm4$
