Question

Complete the table.

f(x) = x2 − 4x
x f(x)
1
2
3
4

Answer 1

To complete the table, we will calculate \( f(x) = x^2 - 4x \) for each given \( x \) value.

1. For \( x = 1 \):
\[
f(1) = 1^2 - 4 \times 1 = 1 - 4 = -3
\]

2. For \( x = 2 \):
\[
f(2) = 2^2 - 4 \times 2 = 4 - 8 = -4
\]

3. For \( x = 3 \):
\[
f(3) = 3^2 - 4 \times 3 = 9 - 12 = -3
\]

4. For \( x = 4 \):
\[
f(4) = 4^2 - 4 \times 4 = 16 - 16 = 0
\]

Now, we can complete the table:

\[
\begin{array}{|c|c|}
\hline
x & f(x) \\
\hline
1 & -3 \\
2 & -4 \\
3 & -3 \\
4 & 0 \\
\hline
\end{array}
\]
