amplitude of-1/3 cos(3x)

amplitude

- \frac{1}{3} cos (3 x)

0.33333 \dots

Solution steps

f (x) = - \frac{1}{3} cos (3 x), A = - \frac{1}{3}

Therefore, the amplitude |A| is

0.33333 \dots

0.33333 \dots

y = \frac{1}{3} x - 5

f (x) = \frac{4}{5} x + 1

\frac{2 x + 3}{x - 2}

f (x) = 2 cos (x) + 1

\frac{2}{x - 3} - \frac{x}{x + 2}
