Solution:
Given
[tex]\begin{gathered} f(x)=x^2-6x+8 \\ \text{And g(x)=}x-2 \end{gathered}[/tex]
We want to solve for f(x) = g(x) using tables of value
To do this, we need to plot tables of values for f(x) and g(x) . The value of x for which f(x) and g(x) have thesame value give the solution to the equation.
The table of value is shown below
From the table of values above,
When x = 2, f(x) = g(x) = 0
Also, When x = 5, f(x) = g(x) = 3
Hence, the solutions to f(x) = g(x) are x = 2 and x = 5
The answer are x = 2 and x = 5
