Will mark the brainliest if answered first and correctly

f(x) is an exponential growth function.  It can be modeled as , where a is the initial amount, r is the interest rate in decimal form, and t is the time period.  When the values from the scenario are plugged in, it looks like .  On a graph, a will be the y-intercept, so the y-intercept of f(x) is 6.

g(x) has a y-intercept that must be less than 6.  The function reaches a y-value of 6 when x = 1, not 0 (when x = 0, we are given the y-intercept).  We see that as y decreases x decreases, so it is confirmed that g(x) has a y-intercept that is < 6.  Already we know that its y-intercept is less than that of f(x).

h(x) visibly intercepts the y-axis at y = 4.  Its y-intercept is 4.

j(x) is written in exponential growth format (like f(x)), where the initial amount, a, would be the y-intercept.  10 is its y-intercept.

After evaluating the y-intercepts of each of these functions, it is determined that j(x) has the highest y-intercept.

The answer is lol i dont know

The variables should add up to equal 1
