Answer 2

2/5****

Answer 3

Alright so the output has to equal 2 for g(x), so that means g(x) has to be equal to two basically. g(x) right now is equal to 4-5x. So we substitute it and make it 4-5x=2. Add the 5x to the other side and it becomes 4=5x+2. Minus the two and get x alone, leaving 5x=2. Now divide both sides by 5 and get the x alone. x equals 2 over 5. This means when you input 2/5 into the equation, the output is 2.
