The question asks for the slope of the function $y = e^x$ at the specific point $x = 10$. The slope of a function at any given point is found by calculating its derivative and evaluating it at that point.
First, determine the derivative of the function $y = e^x$. The derivative of the natural exponential function $e^x$ with respect to $x$ is $e^x$.
The derivative is:
$ \frac{dy}{dx} = \frac{d}{dx}(e^x) = e^x $
Next, evaluate the derivative at the specified value $x = 10$. This gives the slope of the function at that point.
Slope $= \frac{dy}{dx}\Big|_{x=10} = e^{10}$
Thus, the slope of the function $y = e^x$ when $x = 10$ is $e^{10}$.
Consider the hyperbolic functions in Group – 1 and their definitions in Group - 2.
| Group - 1 | Group - 2 | ||
| P | $\tanh x$ | I | $\frac{e^x + e^{-x}}{e^x - e^{-x}}$ |
| Q | $\coth x$ | II | $\frac{2}{e^x + e^{-x}}$ |
| R | $\text{sech } x$ | III | $\frac{2}{e^x - e^{-x}}$ |
| S | $\text{cosech } x$ | IV | $\frac{e^x - e^{-x}}{e^x + e^{-x}}$ |
The correct combination is
