Answer:

  f(x)

Step-by-step explanation:

f(x) apparently has an initial value of 15.

g(x) apparently will have an initial value of 6 or less, since g(1) = 6 and it has increasing slope.

h(0) = 4^0 +3 = 3

j(0) = 10·2^0 = 10

The largest initial value among the initial values {15, <6, 3, 10} is 15.

  f(x) has the largest y-intercept

_____

The graph shows two ways g(x) can be modeled. One is exponential with an initial value of 4; the other is quadratic with an initial value of 6.
