$\"\"$

\

The function is $\"\"$ .

\

The points are in the form of $\"\"$ .

\

Observe the graph:

\

The points are $\"\"$ , $\"\"$ and $\"\"$ .

\

(a).

\

Solve $\"\"$ .

\

The point $\"\"$ is on the graph of the function.

\

The value of the $\"\"$ at $\"\"$ is $\"\"$ .

\

(b)

\

Solve $\"\"$ .

\

The point $\"\"$ is on the graph of the function.

\

The value of the $\"\"$ at $\"\"$ is $\"\"$ .

\

(c)

\

Solve $\"\"$ .

\

The point $\"\"$ is on the graph of the function.

\

The value of the $\"\"$ at $\"\"$ is $\"\"$ .

\

$\"\"$

\

(d)

\

Solve $\"\"$ .

\

The point $\"\"$ is on the graph of the function.

\

The value of the $\"\"$ at $\"\"$ is $\"\"$ .

\

The value of $\"\"$ coordinate of the graph $\"\"$ is greater than $\"\"$ , when the value of $\"\"$ coordinate is greater than $\"\"$ .

\

Hence the solution for $\"\"$ is $\"\"$ or $\"\"$ .

\

(e)

\

Solve $\"\"$ .

\

The point $\"\"$ is on the graph of the function.

\

The value of the $\"\"$ at $\"\"$ is $\"\"$ .

\

The value of $\"\"$ coordinate of the graph $\"\"$ is below $\"\"$ , when the value of $\"\"$ coordinate smaller than $\"\"$ .

\

Hence the solution for $\"\"$ is $\"\"$ or $\"\"$ .

\

(f)

\

Solve $\"\"$ .

\

The point $\"\"$ is on the graph of the function.

\

The value of the $\"\"$ at $\"\"$ is $\"\"$ .

\

The point $\"\"$ is on the graph of the function.

\

The value of the $\"\"$ at $\"\"$ is $\"\"$ .

\

The value of $\"\"$ coordinate of the graph $\"\"$ is in between $\"\"$ and $\"\"$ , when the value of $\"\"$ coordinate are in between $\"\"$ and $\"\"$ .

\

Hence the solution for $\"\"$ is $\"\"$ or $\"\"$ .

\

$\"\"$

\

(a) $\"\"$ .

\

(b) $\"\"$ .

\

(c) $\"\"$ .

\

(d) $\"\"$ or $\"\"$ .

\

(e) $\"\"$ or $\"\"$

\

(f) $\"\"$ or $\"\"$ .
