Answer on Question #58375 – Math – Trigonometry

Question

1. Choose the function whose graph is given by:

$$y = 4 \sin (x + 1) - 2$$ $$y = 4 \cos (x - 1) + 2$$ $$y = 6 \sin (x + 1) - 2$$ $$y = 4 \sin (x - 1) - 2$$

Answer: $y = 4 \sin(x + 1) - 2$.

Question

2. Choose the function whose graph is given by:

$$y = 3 \cos \left(\frac {\pi}{2} x\right)$$ $$y = - 3 \cos (4 x)$$ $$y = 3 \cos (4 x)$$ $$y = 3 \cos \left(\frac {1}{4} x\right)$$

Answer: $y = 3\cos(4x)$.

Question

3. Choose the function whose graph is given by:

$$y = \tan (x - 2) - \frac {\pi}{2}$$ $$y = \tan (x - \pi) - 2$$ $$y = \tan (x - 2) + \pi$$ $$y = \tan x$$

Answer: $y = \tan(x - \pi) - 2$ .

Question

4. Choose the function whose graph is given by:

$y = 3\sec \left(\frac{1}{2} x\right)$

$y = 3c\sec \left(\frac{1}{2} x\right)$

$y = \frac{1}{3}\sec (2x)$

$y = \sec \left(\frac{1}{2} x\right) + 3$

Answer: $y = 3\sec \left(\frac{1}{2} x\right)$ .
