Answer:
- -4
Step-by-step explanation:
Given function
- f(x) = 5x + 12
From the table we get the function g(x), use pairs (1, 10) and (3, 14)
The slope:
- m = (14 - 10)/(3 - 1) = 4/2 = 2
The y-intercept:
- 10 = 2(1) + b
- b = 10 - 2
- b = 8
The function g(x) is found as:
- g(x) = 2x + 8
The y- intercept of f (x) is subtracted from the y-intercept of g (x):
- 8 - 12 = -4
