The functions f(x) and g(x) are described using the following equation and table:

f(x) = 3(1.02)^x
x g(x)
-1 -4
0 6
1 8
2 10

Which statement best compares the y-intercepts of f(x) and g(x)?

The y-intercept of f(x) is equal to the y-intercept of g(x).
The y-intercept of f(x) is equal to 2 times the y-intercept of g(x).
The y-intercept of g(x) is equal to 2 times the y-intercept of f(x).
The y-intercept of g(x) is equal to 2 plus y-intercept of f(x).

Answer:

The y-intercept of g(x) is equal to 2 times the y-intercept of f(x)

Step-by-step explanation:

The functions f(x) and g(x) are described using the following equation and table

[tex]f(x)=3(1.02)^x[/tex]

  x    :   -1        0         1           2    

g(x)  :  -4        6         8          10

f(x)   : 2.94     3       3.06     3.12

We need to compare the y-intercept of f(x) and g(x)

As we know the y-intercept of any function when x=0.

First we find the y-intercept of f(x) and g(x), f(0) and g(0)

y-intercept of g(x), g(0) = 6

y-intercept of f(x), f(0) = 3

6 is 2 times of 3.

Therefore, The y-intercept of g(x) is equal to 2 times the y-intercept of f(x)
