The following points are a minimum and a maximum of a sinusoid. Complete the following steps to model the curve using the sine function.

(4.5, 2), (1.5, 22)

a) What is the vertical shift, k, of this curve?

b) What is the amplitude, a, of this curve?

c) What is period and frequency factor, b, of this curve?

d) Write an equation using the sine function that models this curve.

K= 12

A=10

P= 6

B=pi/3

Equation: y=10sin(pi/3(x))+12

Step-by-step explanation: You can find k by finding the midline, or adding the minimum and maximum y values together and then dividing by 2.

You find a by using the midline value (12) and subtracting it from the maximum y value to get the amplitude.

To find the period, find the difference between the min and max x values, which is 3, then double it to get the full period.

To find the b value, plug it into the 2pi/b=p equation, using the period value you found before you should get pi/3.

When assembling the equation use this format: y=asin[b(x-h)]+k.

You can also graph it with a graphing calculator to check to be sure the max and min points line up.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
