Graph the functions and approximate an x-value in which the exponential function exceeds the polynomial function. y = 4x y = 7x2 + 4x - 2

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.
