What transformation has changed the parent function f(x) = log2x to its new appearance shown in the graph below?

Answer: First Option

−2 • f(x)

Step-by-step explanation:

The function y=log_2(x) passes through point (2,1) since the exponential function 2 ^ x = 2 when x = 1.

Then, if the transformed function passes through the point (2, -2) then this means that f(x) was multiplied by a factor of -2. So if an ordered pair (x_0, y_0) belonged to f(x), then (x_0, -2y_0) belongs to the transformed function. Therefore, if f(x) = log_2 (x) passed through point (2, 1) then the transformed function passes through point (2, -2)

The transformation that multiplies to f(x) by a factor of -2 is:

y = -2 * f (x)

and the transformed function is:

y = -2log_2 (x)

The table shows the ratio of caramel corn to cheddar cornvin a bag. What is the constant propotionality?
zvonat [6]
Since we know is a proportionality, namely a multiplier on "x", we can simply use any of those points, say hmmm let's use 10, 15,

\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad  y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad  variation
\end{array}\\\\
-------------------------------\\\\
\textit{we know that }
\begin{cases}
x=10\\
y=15
\end{cases}\implies 15=k10\implies \cfrac{15}{10}=k\implies \cfrac{3}{2}=k

Lannie ordered 12 copies of the same book for his book club members. The book cost $19 each, and the order has a $15 shipping ch
SashulF [63]

Hey there!

First, we need to find how much Lannie paid for all 12 copies. To do this, all we have to do is multiply the unit price ($19) by how many copies he bought (12)

$19 x 12 = $228

So, he spent $228 on the books, but we also need at add the shipping charge:

$228 + $15 = $243

Therefore, the total cost of Lannie’s order is $243

Hope this helps you!

God bless ❤️

SHORT RESPONSE Two angles of a triangle have measures of 35° and 80°. Find the values of the exterior angle measures of the tria
Oduvanchick [21]

Answer:

Step-by-step explanation:

Before giving the exterior angles, find the third angle. A triangle (all triangles) measure 180 degrees.

35 + 80 + x = 180

115 + x = 180

x = 180 - 115

x = 65

Exterior angles are supplements of the interior angles.

So the exterior angle to 65 degrees is 180 - 65 = 115

And the exterior angle to 35 degrees is 180-35 = 145

The exterior angle to 80 degrees is 180 - 100 = 80

Yakvenalex [24]

Answer:

d=10

Step-by-step explanation:

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Used to find the distance between 2 points.

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

d=\sqrt{(7-1)^2+(-7-1)^2}

d=\sqrt{(6)^2+(-8)^2}

d=\sqrt{36+64}

d=\sqrt{100}

d=10
