Question

Complete the table attached below:task (1) only (complete the table only).

Answer 1

Given the table with different values for "x" and "f":

• You have to multiply the values of "f" and "x" in the same row, in order to find the corresponding values of:

$fx$

Therefore, for:

$x=10\text{ }and\text{ }f=5$$x=9\text{ }and\text{ }f=3$$x=8\text{ }and\text{ }f=2$$x=7\text{ }and\text{ }f=8$

You get these values:

$\begin{gathered} 10\cdot5=50 \\ 9\cdot3=27 \\ 8\cdot2=16 \\ 7\cdot8=56 \end{gathered}$

• Now you need to square each x-value, in order to find the corresponding values for:

$x^2$

You get:

$\begin{gathered} 10^2=100 \\ 9^2=81 \\ 8^2=64 \\ 7^2=49 \end{gathered}$

• Multiply each value obtained in the previous part with the value of "f" of the corresponding row, in order to find the values of:

$fx^2$

You get:

$\begin{gathered} 5\cdot100=500 \\ 3\cdot81=243 \\ 2\cdot64=128 \\ 8\cdot49=392 \end{gathered}$

Hence, the answer is:
