The fact that you must remember is that these points lie on a plane that have a a distance that is ALWAYS an absolute value.  If point A lies on -6 you can have two points that are of a distance 20 points in either direction.  If moving the left, point B can have a value of -26 and moving to the right, point B will have a value of 14.  Hope this is clear!

Good luck!

I need help with this practice I am having a tough time solving it properly
Monica [59]

Given:

There are given that the parent functions as a cosine function:

Where,

The amplitude of the function is 9.

The vertical shift is 11 units down.

Explanation:

To find the cosine function, we need to see the standard form of the cosine function:

f(x)=acos(bx+c)+d

Where,

a is the amplitude of the function,

Now,

According to the question:

The amplitude of the function is 9, which means:

f(x)=9cos(bx+c)+d

The vertical shift is 11 units down, which means:

f(x)=9cos(bx+c)-11

For period:

\begin{gathered} f(x)=-9cos(\frac{12\pi}{7}x+0)-11 \\ f(x)=-9cos(\frac{12\pi}{7}x)-11 \end{gathered}

Final answer:

Hence, the cosine function is shown below;

f(x)=-9cos(\frac{12\pi}{7}x)-11

- 3/4 (x + 2) = 6<br> the / is a fraction can someone help
Oliga [24]
-3/4(x+2)=6
-3/4 is turned into a decimal, -0.75
-0.75(x+2)=6 distribute -0.75 to x and 2 (multiply)
-0.75x-1.5=6 add -1.5 under 6

-0.75x=7.5 divide -0.75 on both sides
-0.75x/-0.75 = 7.5/0.75
x=10
