I'll show you the second line....you should be able to do the rest
Seond line says x = 1 f(x) =x^2 -6x+8 this equals (1)^2 -6(1) +8 = 3
g(x) = x -2 this equals 1 -2 =-1 fill in the chart
Do the same for all of the other x values given Looks like you should find TWO value of x where f(x) and g(x) are equal.....GO !
