Im giving brainliest+60 points aaa there are 4 transformations for each function describe the transformations of each graph. f(x)=-3*2^{x-2} -1 1) 2) 3) 4) f(x)-\frac{1}{4} *2^{x+1} -1 1) 2) 3) 4)

Answers

For the first one.
1) Vertical stretch by a factor of 3.
2) Reflection in the x-axis.
3) Vertical translation of 1 unit down.
4) Horizontal translation of 2 units right.
Second.
1)Vertical compression of 1/4.
2) Reflection in the x-axis.
3)Vertical translation of 1 unit down.
4) Horizontal translation of 1 unit left.

Refer back to the parent function for each transformation.
f(x)= a*2^b(x-h) -k
A = Vertical stretches/Compression
if its -, Reflect in the x-axis
B = Horizontal stretch/compression
if its -, Reflect in the y-axis
H = Horizontal translations
K = Vertical translations

f(x) + n - translate the graph n units up

f(x) - n - translate the graph n units down

f(x + n) - translate the graph n units left

f(x - n) - translate the graph n units right

nf(x) - dilation of the graph along the Oy axis and the scale n

f(nx) - dilation of the graph along the Ox axis and the scale 1/n

-f(x) - symmetry of the graph with respect to the Ox axis

f(-x) - symmetry of the graph with respect to the Oy axis

-----------------------------------------------------------------------------------------------------

[tex]f(x)=-3\cdot2^{x-1}-1\\\\g(x)=2^x\\\\3g(x)=3\cdot2^x-\text{dilatation by a scale of 3}\\\\-3g(x)=-3\cdot2^x-\text{symmetry of the graph with respect to the Ox axis}\\\\-3g(x-1)=-3\cdot2^{x-1}-\text{translate the graph 1 unit right}\\\\-3g(x-1)-1=f(x)=-3\cdot2^{x-1}-1-\text{translate the graph 1 unit down}[/tex]

just say that its a trick question. it has too many transformations to posibly figure out the parent fuction

To shift graph functions to the left: We will be adding inside the function: y= f(x+b) 2. Shift to the right: We will be subtracting inside the function: y= f(x-b) 3. To shift graph up some units: We would be adding outside the function: y= f(x)+b 4.

im alright what do you need

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
