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.
45 x 0.44 = ?
30 x 0.44 = ?
Then add the two answers together.
F(1) = (1)^3 + 2(1)^2 - 5(1) - 6 = 1 + 2 - 5 - 6 = -8; x = 1 is not a solution to the polynomial.
f(-1) = (-1)^3 + 2(-1)^2 - 5(-1) - 6 = -1 + 2 + 5 - 6 = 0; x = -1 is a solution to polynomial.
From the options, a or c has x = -1, both has x = , so lets check for x = 3
f(3) = (3)^3 + 2(3)^2 - 5(3) - 6 = 27 + 18 - 15 - 6 = 24; x = 3 is not a solution to the polynomial.
Therefore the solutions to the polynomial are x = -3, x = -1, x = 2
Answer:
7 dollars
Step-by-step explanation:
Because 1/2 a pound is half of 1 pound and 3.50 is the value of half that pound, you can add 3.50 to 3.50 to get 7 dollars which is the value for 1 pound
