(a)

Observe the graph.

At $\"x=1\"$ , the function is $\"3\"$ units above $\"x-\"$ axis.

Therefore the point $\"(1,$ lies on the graph $\"f(x)\"$ .

Hence, $\"f(1)=3\"$ .

$\"\"$

(b)

Observe the graph.

At $\"x=-1\"$ ,the function is located $\"0.2\"$ units below $\"x-\"$ axis.

Therefore the point $\"(-1,$ lies on the graph $\"f(x)\"$ .

Hence, $\"f(-1)=-0.2\"$ .

$\"\"$

(c)

Find the value of $\"x\"$ where the graph $\"f(x)=1\"$ .

Observe the graph.

$\"f(x)=1\"$ at $\"x=0\"$ and $\"x=3\"$ .

Hence, $\"f(0)=1\"$ and $\"f(3)=1\"$ .

$\"\"$

(d)

Find the value of $\"x\"$ where the graph $\"f(x)=0\"$ .

Observe the graph.

$\"f(x)=0\"$ at $\"x=-0.8\"$ .

Hence, $\"f(-0.8)=0\"$ .

$\"\"$

(e)

The domain of $\"f\"$ consists of all values of $\"x\"$ on the graph of $\"f\"$ .

$\"f(x)\"$ is defined for $\"-2\\leq$ .

The domain of $\"f\"$ is $\"\\left$ .

The range of $\"f\"$ consists of all values of $\"y\"$ on the graph of $\"f\"$ .

$\"f\"$ takes all the value from $\"-1\"$ to $\"3\"$ .

The range of $\"f\"$ is $\"\\left$ .

$\"\"$

(f)

Observe the graph.

$\"f(x)\"$ increases for all the values of $\"x\"$ between $\"-2\\leq$

$\"f(x)\"$ increases on the interval $\"\\left$ .

(a) $\"f(1)=3\"$ .

(b) $\"f(-1)=-0.2\"$ .

(c) $\"x=0\"$ and $\"x=3\"$ .

(d) $\"f(x)=0\"$ at $\"x=-0.8\"$ .

(e) Domain of $\"f\"$ is $\"\\left$ and range of $\"f\"$ is $\"\\left$ .

(f) $\"\\left$ .
