Which polynominal does the model represent
-x^3+2x^2-3x+2
x^2+x-2
-x^2-x+2
-x^2+x-2
Have you tries to figure it out?
Hmm, let me put on my math hat and give you an answer with a touch of humor.
Out of all the options, the polynomial representing the model is as special as a clown's hat. Drumroll, please! 🥁 It's -x^3 + 2x^2 - 3x + 2. That's right, it's a cubic polynomial that's ready to party! 🎉 The other options might make you do a double-take, but this one is the real deal.
To determine which polynomial the model represents, we need to compare the coefficients of each polynomial term.
Model polynomial: -x^3 + 2x^2 - 3x + 2
Let's compare the coefficients:
Coefficient of x^3:
In the model polynomial, the coefficient of x^3 is -1.
Coefficient of x^2:
In the model polynomial, the coefficient of x^2 is 2.
Coefficient of x:
In the model polynomial, the coefficient of x is -3.
Coefficient of constant term:
In the model polynomial, the constant term is 2.
Now let's compare these coefficients with the given options:
Option 1: x^2 + x - 2
The coefficient of x^3 in this option is 0 (not the same as the model).
The coefficient of x^2 in this option is 1 (not the same as the model).
The coefficient of x in this option is 1 (not the same as the model).
The constant term in this option is -2 (not the same as the model).
Option 2: -x^2 - x + 2
The coefficient of x^3 in this option is 0 (not the same as the model).
The coefficient of x^2 in this option is -1 (not the same as the model).
The coefficient of x in this option is -1 (not the same as the model).
The constant term in this option is 2 (same as the model).
Option 3: -x^2 + x - 2
The coefficient of x^3 in this option is 0 (not the same as the model).
The coefficient of x^2 in this option is -1 (same as the model).
The coefficient of x in this option is 1 (same as the model).
The constant term in this option is -2 (same as the model).
Based on the comparison, the model polynomial represents option 3: -x^2 + x - 2.
To determine which polynomial the model represents, we need to match the equation of the model to the given polynomial options. Let's go through each option one by one:
Option 1: -x^3 + 2x^2 - 3x + 2
Option 2: x^2 + x - 2
Option 3: -x^2 - x + 2
Option 4: -x^2 + x - 2
To match the equation of the model to the given options, we need to compare the coefficients of the terms. Let's break down the model equation and compare it to each option:
Model equation: -x^3 + 2x^2 - 3x + 2
1. Looking at the highest degree term:
Model: -x^3
Option 1: -x^3
There is a match.
2. Next, let's look at the second-highest degree term:
Model: 2x^2
Option 2: x^2
Option 3: -x^2
Option 4: -x^2
None of the options match.
3. Moving on to the next term:
Model: -3x
Option 2: x
Option 3: -x
Option 4: x
None of the options match.
4. Lastly, let's check the constant term:
Model: 2
Option 2: -2
Option 3: 2
Option 4: -2
None of the options match.
Based on the comparison, none of the given options match the equation of the model. Therefore, the model does not represent any of the provided polynomials.
