Answer:

  C  y=2cos(2π/3t)

Step-by-step explanation:

The amplitude of the function will be half the difference between the minimum and maximum: 4/2 = 2.

The multiplier of t in the function will be 2π/period = 2π/3.

What transformation has changed the parent function f(x) = log3x to its new appearance shown in the graph below?
Wittaler [7]

Answer : option B

Parent Graph f(x) = log_3(x) is attached below

We analyze each option

A) f(x − 2) --> x - 2 shifts the graph 2 units to the right

B) f(x + 2) --> x + 2 shifts the graph 2 units to the left

C) f(x) − 2 --> f(x) - 2 shifts the graph 2 units down

D) f(x) + 2 --> f(x) + 2 shifts the graph 2 units up

In the graph of f(x)= log_3(x) , the x intercept at x=1

From the graph attached in the question, the x intercept at x=-1

Its means the parent graph is shifted 2 units to the left.

Option B: f(x + 2) --> x + 2 shifts the graph 2 units to the left

What are the coordinates of the midpoint of the segment whose endpoint are P(-6, 3) and Q(9, -11)
poizon [28]

Answer:

\large\boxed{C.\ (1.5,\ -4)}

Step-by-step explanation:

The formula of a midpoint of a segment AB with endpoints at A(x₁, y₁) and B(x₂, y₂):

M_{AB}\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)

We have the points P(-6, 3) and Q(9, -11).

Substitute:

M_{PQ}(x,\ y)\\\\x=\dfrac{-6+9}{2}=\dfrac{3}{2}=1.5\\\\y=\dfrac{3+(-11)}{2}=\dfrac{-8}{2}=-4
