You can put this solution on YOUR website! f(x) = 6 - 4x
f(x) = 8
this means that:
8 = 6 - 4x
subtract 6 from both sides of this equation to get:
2 = - 4x
divide both sides of this equation by -4 to get:
-(2/4) = x
value of x is equal to -(1/2)
plug that into your original equation of:
f(x) = 6 - 4x to get:
f(x) = 6 - 4 * (-1/2) which becomes:
f(x) = 6 + (4/2) which becomes:
f(x) = 6 + 2 which becomes:
f(x) = 8
when x = -(1/2), f(x) = 8
