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.
Remark
Thank you for editing your question. Very few people do and those of answering don't really like reporting incomplete questions (or I don't).
You could write it like this.
Solve Multiply both sides by 7
x > 800 * 7
x > 5600 That would make the inequality equal to 800 if x = 5600.
You need to go just 1 step further. Try 5607. When you divide that by 7, you get 5607/7 = 801 which is 1 bigger than 800.
