I the northern hemisphere is cool right now and I think I am going to be able to text you back.
To find the values of a and b, we can use the given information about the function f(x) and its derivatives at x = 0.
First, we know that the value of f(0) is 1, which means that when we plug x = 0 into the function, we get f(0) = 20 + a0 + b*0^2 - 0 + 2 = 1. Solving this equation for b, we get b = -1.
Next, we know that the derivative of the function f(x) at x = 0 is ƒ'(0) = 1. The derivative of a polynomial function is given by ƒ'(x) = 2x + ax + bx^2 - 1. Plugging in x = 0, we get ƒ'(0) = 20 + a0 + (-1)*0^2 - 1 = 1. Solving for a, we get a = 1.
Therefore, the values of a and b are a = 1 and b = -1. The sum of these values is a + b = 1 + (-1) = 0.
One of the examples from the text that can be regarded as clear, logical and sincere is:
- The speaker said, this nation would endure, revive and prosper.
He goes to say that they only thing that they had to fear was fear itself. He said this to show that fear may keep them from advancing when they should have done so.
The president used the words such as revive to show that the nation was still capable of enduring and coming out of the dark times that they were in.
From these words we can see that the president was logical and also sincere in what they were passing through and how they were to overcome it.
<h3>What is a clear, Logical and sincere quote?</h3>
