Step 1.2.1.1

Raising $0$ to any positive power yields $0$ .

$f (0) = 3 \cdot 0 - 3$

Step 1.2.1.2

Multiply $3$ by $0$ .

$f (0) = 0 - 3$

Step 1.2.2

Subtract $3$ from $0$ .

$f (0) = - 3$

Step 1.2.3

The final answer is $- 3$ .

$- 3$

Step 2

Since $- 3$ $\neq$ $4$ , the point is not on the graph.

The point is not on the graph
