Step-by-step explanation:
From the table of function given, you would observe that if you subtract 2 from half of the x-variable values, you'd get the y-variable values.
For example, half of -8 = -4. If you add 2 to -4, you'd get: -4 + 2 = -2. Same applies to other x-values on the table.
Thus, an expression for the function represented by the table values can be written as,
Expanding the given expressions using Foil:
1)(–7x + 4)(–7x + 4) =
2) (–7x + 4)(4 – 7x)=
3)(–7x + 4)(–7x – 4)==
4)(–7x + 4)(7x – 4)=
The third option that is (–7x + 4)(–7x – 4) is difference of two squares.
