Which of the following transforms y=x2 to the graph of y=(x+5)2? a translation 5 units to the right a translation 5 units to the left a translation 5 units down a translation 5 units up

We define transformations as operations that act on functions and modify them in some way. Here we will see translations, which is a type of transformation that moves the whole graph in some direction.

We will see that this is a translation of 5 units to the left.

To solve this, first, we need to describe what a horizontal translation is.

For a given function f(x) a horizontal translation of N units is written as:

g(x) = f(x + N).

So here we start wit:

f(x) = x^2

And then we have:

g(x) = (x + 5)^2

Then we can see that:

g(x) = f(x + 5).

From this, we can conclude that N = 5, thus we have a translation of 5 units to the left.

Translation 5 units to the left

The "x+5" replaces the "x", meaning that the xy axis moves 5 units to the right. If the parabola stays still, then a point like (0,0) moves to (-5,0) after you move the xy axis 5 units to the right. If the xy axis stays still, then it gives the illusion that the entire parabola moves 5 units to the left.

Check out the graph below for the comparison of the two graphs. Note that the blue graph moves 5 units to the left to get the red graph. In other words, every point on the blue graph moves 5 units to the left to get a corresponding point on the red graph.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
