Answer 1

Answer on Question #58367 – Math – Trigonometry

Question 1

Choose the function whose graph is given by:

$$y = \cos x - 2$$ $$y = - \sin x - 2$$ $$y = \sin x - 2$$ $$y = - \cos x - 2$$

Answer: $y = \sin x - 2$.

Question 2

Choose the function whose graph is given by:

$y = \cos (x + 1)$

$y = \sin x + 2$

$y = \cos x + 1$

$y = \cos x + 2$

Answer: $y = \cos x + 1$.

Question 3

Choose the function whose graph is given by:

$y = \cos x - 1$

$y = \cos (x + 1)$

$y = \cos (x - 1)$

$y = \sin (x - 1)$

Answer: $y = \cos(x - 1)$.

Question 4

The graph of $y = 4\sin(x + 3) - 2$ is obtained by shifting the graph of $y = 4\sin x - 2$ horizontally 3 units to the left.

True

False

Answer: True.

Question 5

Choose the function whose graph is given by:

$$y = \cos (2 x)$$ $$y = \cos \left(\frac {1}{4} x\right)$$ $$y = \cos (4 x)$$ $$y = \cos \left(\frac {1}{2} x\right)$$

Answer: $y = \cos(4x)$ .
