Identify the sine function with the given attributes.

Thepotemich [5.8K]

Answer:

Last option

$f(t)=sin(\pi(t -3)) + 4$

Step-by-step explanation:

The general sine function has the following form

$y = Asin(bt-\phi) + k$

Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.

$\frac{2\pi}{b}$ is the period: time it takes the wave to complete a cycle.

k is the vertical displacement.

$\phi$ phase shift

We know that:

amplitude: 1; period: 2; phase shift: 3; vertical shift: 4

Thus:

$A =1$

$\frac{2\pi}{b}=2$

$b=\pi$

$\phi=3$

$k=4$

Then the function is:

$f(t)=sin(\pi(t -3)) + 4$

The answer is last option

Could someone please explain how to plot the x-intercept of the first equation and what the answer would be?

Elis [28]

Answer:

You would start in the middle of the number line, move right to positive 4x then move up 2 units to land right in line with 2y this is where your plot would be.
