1. Describe the transformations necessary to transform the graph of

lana66690 [7]

Answer:

- The function $f(x)$ must be shifted right 1 unit.

- The function $f(x)$ must be shifted up 4 units.

- The function $f(x)$ must be stretched vertically by a factor of 3.

Step-by-step explanation:

There are some transformations for a function f(x):

If $f(x)+k$ , then the function is shifted up "k" units.

If $f(x)-k$ , then the function is shifted down "k" units.

If $f(x+k)$ , then the function is shifted left "k" units.

If $f(x-k)$ , then the function is shifted right "k" units.

If $bf(x)$ and $b>1$ , then the function is stretched vertically by a factor of "b".

If $bf(x)$ and $0$ , then the function is compressed vertically by a factor of "b".

In this case we have the following parent function $f(x)$ :

$f(x)=x^2$

And the function $g(x)$ :

$g(x) = 3(x - 1)^2 + 4$

Based on the explained before, we can describe the transformations necessary to transform the graph of $f(x)$ to the graph of $g(x)$ :

- The function $f(x)$ must be shifted right 1 unit.

- The function $f(x)$ must be shifted up 4 units.

- The function $f(x)$ must be stretched vertically by a factor of 3.

PLEASE HELP i don’t want to failllll this time!

Arlecino [84]

Answer:

C. 115°,65°

Step-by-step explanation:

Make the equation for ∠A equal the equation for ∠C: 100+5x=106+3x. You will find x=3. So you plug that into the equations for ∠A and ∠C. And you know that ∠A and ∠C both equal 115°. You repeat these steps for angles B and D and they equal 65°. Ya welcome.
