The graph of a sinusoidal function has a minimum point at (0,3)(0,3) and then intersects its midline at (5π,5)
bekas [8.4K]

Answer: F(x) = 2*sin(x/10  +(3/2)*pi) + 5

Step-by-step explanation:

The information that we have is that:

We have a minimum at (0, 3)

the midline is at (5*pi, 5)

This is a sinusoidal function, so we can write one generic one as:

F(x) = A*sin(c*x + p) + B.

where A and B are constants, c is the frequency and p is a phase

First, the minimum of the sine function is when sin(x) = -1, and this happens at (3/2)*pi

We know that this minimum is at x = 0.

sin(c*0 + p) = -1

Then p = 3/2*pi.

So our function is:

F(x) = A*sin(c*x  +(3/2)*pi) + B.

Now, we know that F(0) = 3, so:

3 = A*sin(c*0 +(3/2)*pi) + B = -A + B.

now we can use the other hint, the midpoint of the sine function is when sin(x) = 0, and this happens at x = 0 and x = pi, particularlly as we here have a phase of 3/2*pi, we should find x = 2*pi.

then:

c*5*pi + (3/2)*pi = 2*pi

c*5 + 3/2 = 2

c*5 = 2 - 3/2 = 1/2

C = 1/2*5 = 1/10

So our function is

F(x) = A*sin(x/10  +(3/2)*pi) + B

and we know that when x = 5*pi, F(5*pi) = 5, so:

5 = F(x) = A*sin(5*pi/10  +(3/2)*pi) + B

5 = B

and we aready knew that:

- A + B = 3

-A + 5 = 3

A = 5 - 3 = 2

So our equation is:

F(x) = 2*sin(x/10  +(3/2)*pi) + 5

Which of the following terms has the coefficient with the largest value?
katovenus [111]

Answer:

C: 2x^5

Step-by-step explanation:

Leading coefficients are the numbers written in front of the variable with the largest exponent. Just like regular coefficients, they can be positive, negative, real, or imaginary as well as whole numbers, fractions or decimals. For example, in the equation -7x^4 + 2x^3 - 11, the highest exponent is 4.

Use the graph to determine the input value for which f(x) = g(x) is true.
Alex_Xolod [135]

we know that

In the graph the intersection both functions is the point when f(x)=g(x)

so

see the graph

the point of intersection both graphs is (1.5,2)

that means

for the input value of x=1.5

f(1.5)=g(1.5)=2

therefore

<u>the answer is</u>

the input value is x=1.5

(4,-2) m=-1 how can you graph this
Svet_ta [14]
Ok, so assuming you know what the slope of -1 looks like

a bit like \ except more diagonal

you look for point (4,-2), then you draw the -1 slope from it

it should cross through points (5,-3) and (3,-1)
