$f (x) = 3 (5^{x}) - 5$

Langkah 1

Kalikan $3$ dengan $5^{x}$ .

$f (x) = 3 \cdot 5^{x} - 5$

Langkah 2

The word linear is used for a straight line. A linear function is a function of a straight line, which means that the degree of a linear function must be $0$ or $1$ . In this case, The degree of $f (x) = 3 \cdot 5^{x} - 5$ is $- 1$ , which makes the function a nonlinear function.

$f (x) = 3 \cdot 5^{x} - 5$ is not a linear function
