$\"\"$

\

The functions are $\"\"$ and $\"\"$ .

\

(a)

\

Graph the functions $\"\"$ and $\"\"$ in same cartesian plane.

\

Graph the functions $\"\"$ and $\"\"$ .

\

$\"\"$

\

$\"\"$

\

(b)

\

Solve for $\"\"$ .

\

Find the intersection point on the graph.

\

Equate $\"\"$ and $\"\"$ .

\

$\"\"$

\

Apply logarithm on each side.

\

$\"\"$

\

Apply logarithm power property : $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Therefore, the solution is $\"\"$ .

\

Substitute $\"\"$ in $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Therefore, the intersection point is $\"\"$ .
