Langkah 1.1

Gabungkan $x^{2}$ dan $\frac{8}{7}$ .

$f (x) = 7 - \frac{x^{2} \cdot 8}{7}$

Langkah 1.2

Pindahkan $8$ ke sebelah kiri $x^{2}$ .

$f (x) = 7 - \frac{8 x^{2}}{7}$

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 $f (x) = 7 - \frac{8 x^{2}}{7}$ is $2$ , which makes the function a nonlinear function.

$f (x) = 7 - \frac{8 x^{2}}{7}$ is not a linear function
