What is the inverse of the relation {(-3, 5), (2, -2), (0, 1)}?
olya-2409 [2.1K]
The inverse of a relation just switches the x and y values.
{(-3,5), (2,-2),(0,1)}
Inverse = {(5,-3),(-2,2),(1,0)}

What transformations are needed to change the parent cosine function to y=3cos(10(x-pi))?
LUCKY_DIMON [66]

Answer:

The graph of y=cos(x) is:

*Stretched vertically by a factor of 3

*Compressed horizontally by a factor  \frac{1}{10} .

*Moves horizontally \pi units to the rigth

The transformation is:

y=3f(10(x-\pi))

Step-by-step explanation:

If  the function y=cf(h(x+b))  represents the transformations made to the graph of y= f(x)  then, by definition:

If  0 then the graph is compressed vertically by a factor c.

If  |c| > 1 then the graph is stretched vertically by a factor c

If c  then the graph is reflected on the x axis.

If b> 0 The graph moves horizontally b units to the left

If b The graph moves horizontally b units to the rigth

If 0 the graph is stretched horizontally  by a factor \frac{1}{h}

If h> 1 the graph is compressed horizontally by a factor \frac{1}{h}

In this problem we have the function y=3cos(10(x-pi)) and our parent function is y = cos(x)

The transformation is:

y=3f(10(x-\pi))

Then c =3>1  and b =-\pi < 0 and h=10 > 1

Therefore the graph of y=cos(x) is:

Stretched vertically by a factor of 3.

Also as h=10 the graph is compressed horizontally by a factor  \frac{1}{10} .

Also, as b =-\pi < 0 The graph moves horizontally \pi units to the rigth
