amplitude of y= 1/2 cos(2pix)

amplitude

y = \frac{1}{2} cos (2 π x)

0.5

Solution steps

f (x) = \frac{1}{2} cos (2 π x), A = \frac{1}{2}

Therefore, the amplitude |A| is

0.5

0.5

\frac{2 x ^{2} - 7 x - 15}{x ^{2} - 3 x - 10}

5 x + 2 y = 8

y = \frac{1}{4} x^{2} + x

f (x) = - 3 x + 1

y = 4 x - 8, (0, 5.5)
