Answer:
The Exponential function is

And the polynomial function is

And, we have to find the value of x for which, exponential function exceeds the polynomial function which can be written as

1. When , x= -1
LHS

RHS

2. When , x=0
L HS

RHS

3. When ,x= 0.5
L HS

RHS

4. When , x=2
LHS

RHS

The Minimum value for which exponential function exceeds the polynomial function is , x= 0.5
But,there is other value for which exponential function exceeds the polynomial function is , x=2.

that is what you're solving and the answer, I turned 3/4 into 75% then divided
I think it is $900 because .15* 6000 is 900. This means Victoria needs to pay $900. <span />
