Solution

Let's complete the table for the given function f(x)=3x2+3xf(x) = -3x^2 + 3x. We'll evaluate f(x)f(x) for each of the values of xx provided in the table.

Step-by-step calculation:

  1. For x=0x = 0: f(0)=3(0)2+3(0)=0f(0) = -3(0)^2 + 3(0) = 0 So, f(0)=0f(0) = 0.

  2. For x=1x = 1: f(1)=3(1)2+3(1)=3(1)+3=0f(1) = -3(1)^2 + 3(1) = -3(1) + 3 = 0 So, f(1)=0f(1) = 0.

  3. For x=2x = 2: f(2)=3(2)2+3(2)=3(4)+6=12+6=6f(2) = -3(2)^2 + 3(2) = -3(4) + 6 = -12 + 6 = -6 So, f(2)=6f(2) = -6.

  4. For x=3x = 3: f(3)=3(3)2+3(3)=3(9)+9=27+9=18f(3) = -3(3)^2 + 3(3) = -3(9) + 9 = -27 + 9 = -18 So, f(3)=18f(3) = -18.

The completed table is:

\hline x & f(x) \\ \hline 0 & 0 \\ 1 & 0 \\ 2 & -6 \\ 3 & -18 \\ \hline \end{array}$$ Would you like further details or have any questions? Here are 5 related questions to expand your understanding: 1. What is the vertex of the quadratic function $$f(x) = -3x^2 + 3x$$? 2. How do you find the axis of symmetry for this function? 3. What is the range of $$f(x) = -3x^2 + 3x$$? 4. Can you determine where $$f(x)$$ is increasing and decreasing? 5. How would the graph of $$f(x) = -3x^2 + 3x$$ look like? **Tip:** The coefficient of $$x^2$$ determines whether a parabola opens upwards or downwards. Here, $$-3$$ makes it open downward!
