In general, the point on the graph of the function f(x) = a×b^x.

Option A (0,a)

Step-by-step explanation:

we know that

Is a exponential function

where

a is the initial value

b is the base

Remember that

The initial value is the value of the function when the value of x is equal to zero (y-intercept)

therefore

For x=0

The y-intercept is the point (0,a)

yes. we do proportions in probabilities.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
