Y = -x + 2
y = 3x + 1
-x + 2 = 3x + 1
+ x + x
2 = 4x + 1
- 1 - 1
1 = 4x
4 4
¹/₄ = x
y = 3x + 1
y = 3(¹/₄) + 1
y = ³/₄ + 1
y = 1³/₄
(x, y) = (¹/₄, 1³/₄)
The answer is A.
Explanation:
To answer a question like this, refer to the definitions of the functions:
(f-g)(200) is ...
... the difference between the amount of money a cell phone screen is being sold for and the cost of production, when 200 screens are being manufactured.
__
The numerical value of (f-g)(200) is ...
f(200) -g(200) = (3·200 +5000) -(20·200 -400) = 5600 -3600
(f-g)(200) = 2000
