Answer:
y = cot(x - ⅓π) + 2
Step-by-step explanation:
The general equation for a cotangent function with the given properties is
y = Acot(Bx + C) + D, where
A = the stretching factor
π/|B| = the period
C = the phase shift (negative is to the right)
D = the vertical shift
A = 1
π/|B| = π, so1/|B| = 1 and B = 1
C = -⅓π
D = 2
The function is
y = cot(x - ⅓π) + 2
The figure below shows the graph of the function with the given parameters.
Note that the parent function y = cot(x) has the y-axis as an asymptote, so we can measure the phase shift by the movement of the asymptote π units to the right.
The part that would change would be the number 2. It would become a 3 instead of the 2. Tripling something means to have 3 groups of it.
The reason is that the $50 is not changing, nor would the number of weeks, x be changing.
Answer:
<em>y = - 4x + 38 </em>
Step-by-step explanation:
A(3, 9)
B(5, 1)
=
= - 4
CD║AB
C(9, 2)
y - 2 = - 4(x - 9)
<em>y = - 4x + 38</em>
I got the median was 39 sorry if it is wrong
