Math Problem Statement

nakresli 2 grafy k charakteristikám exponenciálních funkcí: Charakteristika:

Pokud je a>1a>1 (např. 2x2x), funkce roste. To znamená, že jakmile zvýšíme xx, hodnota f(x)f(x) se zvyšuje.

Pokud je 0<a<10<a<1 (např. (1/2)x(1/2)x), funkce klesá. To znamená, že jakmile zvýšíme xx, hodnota f(x)f(x) se snižuje.

Solution

Here are the two graphs illustrating the characteristics of exponential functions:

  1. Growing Exponential Function (a > 1): This graph shows a function like f(x)=2xf(x) = 2^x, which rises sharply as xx increases.

  2. Decaying Exponential Function (0 < a < 1): This graph shows a function like f(x)=(1/2)xf(x) = (1/2)^x, which decreases and approaches zero as xx increases.

Tip: When working with exponential functions, remember that the base determines the growth or decay rate: a base greater than 1 leads to growth, while a base between 0 and 1 results in decay.
