Answer:
8/3
Step-by-step explanation:
equation of f(x) = -3x +3
slope of g(x) is the negative reciprocal of the slope of f(x)
slope of g(x) = 1/3
let us find the y-intercept of g(x) using the point (1,3)
y= mx + b
3 = 1/3 (1) + b
3-(1/3) = b
8/3 = b
g(x) = 1/3x + 8/3
g(0) = 8/3
( g(0) is nothing but the y-intercept of function g(x))
