What is the initial value for the function f(x)=3(5/4)x

For

you seem to want to know the value of f(0). Put 0 where x is, then evaluate.


The initial value of the function is 3.

_____
You will observe that when x=0, the exponential term evaluates to 1. This is true regardless of its base. Thus f(0) is always the coefficient of the exponential term—in this case, 3.

If you meant for f(x)=3(5/4)x to represent an exponential function, please use " ^ " to indicate exponentiation:

f(x)=3(5/4)^x

The initial value is the value of f(x) when x = 0:  f(0) = 3(5/4)^0 = 3(1) = 3.

I’m guessing that the answer is c, but i’m not sure which grid is being talked about. since 5x5= 25 and 3x3= 9 (which there are no answers for). a is not right because while the ratio is the same, 6/25= 0.24 which is equal to 24% not 30%.
