Answer:

  A. y-intercept should be (0, -6)

Step-by-step explanation:

The slope-intercept form of the equation for a line is ...

  y = mx + b

where m is the slope and b is the y-intercept. These parameters in your equation are ...

  m = -3/4

  b = -6

This means the y-intercept is at y = -6. Written as an ordered pair, the point is ... (0, -6).

  In Step 1, the y-intercept should be (0, -6).

What is the student's error?
Trava [24]

Answer:

Two x's can have the same y, but an x cannot have different y's. For example, [(2,3)(-2,4)(3,3)(5,18)] is a function because all of the x's have a specific y, and there is not more than one y to an x. However, [(2,3)(-3,7)(2,-4)] is not a function because one of the x's has more than one y.

Step-by-step explanation:

(hope this helps-you can just put the first sentence...the rest is kinda wordy :P)

Write a cosine function that has a midline of 2, an amplitude of 4 and a period of 4/7
ella [17]

Answer:

y= 4cos(\frac{7\pi }{2}x)+2

Step-by-step explanation:

We know that the transformations of a cosine equation can be shown as:

y=±a(b(x-h))+k

Where 'a' is the amplitude

'b' is the horizontal change (Do 2π/b to find the period)

'h' is the horizontal shift

and 'k' is the vertical shift or midline.

------------------------------------------------------

If the amplitude is 4, we can assume a=4.

Since the period is 4/7, we can solve for the 'b' value by:

2\pi /\frac{4}{7}= \frac{7\pi }{2}

Next, since the midline is 2, we know that a vertical shift of 2 occurred. Thus, the 'k' value is 2.

Writing this equation gives us:

y= 4cos(\frac{7\pi }{2}x)+2
