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

Give the domain and range.

yaroslaw [1]

Given:

The graph.

To find:

The domain and range of the graph.

Solution:

The three points on the graph are (-3,3), (0,0) and (3,3).

We know that, domain is the set of input values or x-values. So,

Domain = {-3,0,3}

We know that, Range is the set of output values or y-values. So, elements for range are 3,0,3. But a set contains only distinct elements. So, consider 3 once in range.

Range = {0,3}

Therefore, the correct option is b.
