Answer:
The y-intercepts are the same and the slope of f(x) is greater than g(x)
Explanation:
1) Make an equation for f(x)
 y- intercept = 1 ( 0 , 1 )
 Slope: 4x
 

 =
 = 
 = 4
 = 4
Equation: f(x) = 4x + 1
2) Comparing the y-intercepts
 y = mx + b
 g(x) = 3x + 1
 f(x) = 4x + 1
3) Comparing slopes
 g(x) = 3x + 1
 f(x) = 4x + 1
