Exploring the Representative Curve of a Given Function

In mathematics, functions are used to describe the relationship between variables. A function can be represented graphically as a curve in a coordinate system. In this article, we will explore the representative curve of a given function, denoted as (C), in an orthonormal system of axes (O; i, j). The function is defined as $f(x) = \ln(e^{2x} - e^x + 1) - 1$ , where $x$ is a real number.

The given function is a composite function, which means it is a combination of two or more functions. In this case, the function is a combination of the natural logarithm function and the exponential function. The natural logarithm function is defined as $\ln(x) = \log_e(x)$ , where $x$ is a positive real number. The exponential function is defined as $e^x = \sum_{n=0}^{\infty} \frac{x^n}{n!}$ , where $x$ is a real number.

To understand the behavior of the function, let's analyze its components. The function $e^{2x} - e^x + 1$ is a quadratic function in terms of $e^x$ . The quadratic function can be factored as $(e^x - 1)^2 + 1$ . This means that the function $e^{2x} - e^x + 1$ is always greater than or equal to 1, and it has a minimum value of 1 when $e^x = 1$ .

The function $f(x) = \ln(e^{2x} - e^x + 1) - 1$ has several properties that are worth noting.

Domain: The domain of the function is all real numbers, denoted as $\mathbb{R}$ .
Range: The range of the function is all real numbers, denoted as $\mathbb{R}$ .
Continuity: The function is continuous for all real numbers.
Differentiability: The function is differentiable for all real numbers.

The representative curve of the function is denoted as (C). To find the representative curve, we need to find the values of $x$ and $y$ that satisfy the equation $y = f(x)$ .

Let's start by finding the values of $x$ that satisfy the equation $e^{2x} - e^x + 1 = 1$ . This equation can be simplified to $e^{2x} - e^x = 0$ . This equation has two solutions: $x = 0$ and $x = -\infty$ .

Now, let's find the values of $y$ that satisfy the equation $y = f(x)$ . We can substitute the values of $x$ that we found earlier into the equation $y = f(x)$ .

For $x = 0$ , we have $y = f(0) = \ln(e^0 - e^0 + 1) - 1 = \ln(1) - 1 = -1$ .

For $x = -\infty$ , we have $y = f(-\infty) = \ln(e^{-\infty} - e^{-\infty} + 1) - 1 = \ln(1) - 1 = -1$ .

The representative curve of the function has two asymptotes: $x = -\infty$ and $y = -1$ .

The asymptote $x = -\infty$ is a vertical asymptote, which means that the curve approaches the asymptote as $x$ approaches $-\infty$ .

The asymptote $y = -1$ is a horizontal asymptote, which means that the curve approaches the asymptote as $y$ approaches $-\infty$ .

The representative curve of the function has two intercepts: $(0, -1)$ and $(-\infty, -1)$ .

The intercept $(0, -1)$ is a point on the curve where the curve intersects the $y$ -axis.

The intercept $(-\infty, -1)$ is a point on the curve where the curve intersects the $x$ -axis.

In this article, we explored the representative curve of a given function, denoted as (C), in an orthonormal system of axes (O; i, j). The function is defined as $f(x) = \ln(e^{2x} - e^x + 1) - 1$ , where $x$ is a real number. We analyzed the properties of the function, including its domain, range, continuity, and differentiability. We also found the values of $x$ and $y$ that satisfy the equation $y = f(x)$ , and we identified the asymptotes and intercepts of the representative curve.
