$\"\"$

(a)

The function is $\"\"$ .

Rewrite the function as $\"\"$ .

Plotting points method is preferred.

Make the table of values to find ordered pairs that satisfy the equation.

Choose values for $\"\"$ and find the corresponding values for $\"\"$ .

This is linear function form in quadratic general equation form.

So, the plotting points method use to graph a function.Zero function of f is $\"\"$ .

$\"\"$

$\"\"$ .

The function $\"\"$ graph is

$\"graph$

$\"\"$

(b)

The function $\"\"$ .

This is quadratic family function.

So, the translating method use to graph a function. The parent function $\"\"$ .

The graph of $\"\"$ is a horizontal shift of one unit to the right followed by a vertical stretch followed by a downward shift of six units of the graph of $\"\"$ . $\"\"$

The function $\"\"$ and $\"\"$ , graph is

$\"graph$
