Answer:
A. 10 units
Explanation:
The y-intercept of f(x) is f(0) = -9.
The y-intercept of g(x) is g(0) = g(1)/2 = 1.
The distance between these points is ...
1 -(-9) = 10 . . . units
__
We notice that the common ratio of the table values of g(x) is 4/2=2, so the value for x=0 will be a factor of 2 less than the value for x=1.
