To do this, we have to solve the equation 3 times for 3 different values for f(x).
Those three numbers are -2, 2, and 4, the numbers in the range.
First solve for -2.
-2 = -2x + 6
Subtract 6 from each side:
-8 = -2x
Divide by -2 on each side:
4 = x That's one value done.
Next, solve with 2.
2 = -2x + 6
Subtract 6 from both sides.
-4 = -2x
Divide each side by -2.
2 = x Second value solved for.
Last value: 4.
4 = -2x + 6
Subtract 6 from each side.
-2 = -2x
Divide each side by -2.
1 = x. Now just put the domain together.
Domain is this:
{4, 2, 1}.
Hope this helps!
