Photomath is the best for fractions, decimals ect. You could also try a scientific calculator.
Let's eliminate x. To achieve this, mult. the 2nd equation by 2, obtaining
-8x + 2y = 10. Now add this result to the first equation:
8x-2y= -10
-8x + 2y = 10
---------------------
0
The two equations actually represent the same line. Without an x- or a y-value, we cannot solve for the value of the other variable. There are infinitely many solutions.

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.
