Since I can't view the image you attached, I'll just provide you a guide for solving the scale factor:


To find<span> a </span>scale factor<span> between two similar figures,</span>find<span> two corresponding sides and write the ratio of the two sides. If you begin with the smaller </span>figure, yourscale factor<span> will be less than one. If you begin with the larger </span>figure<span>, your </span>scale factor<span> will be greater than one.</span>

Answer:

In the figure we can see that the dilation is an enlargement from the black figure to the blue figure.

The factor would be found by taking two points and dividing them. For example, at the right side we have that the point was from x=2 to x=4, their division would be 4/2=2. Now, we take the point in the left side x=-1 and x=-2, if we divide them we have -2/-1=2.

Therefore, the scale factor is 2.

Can you please help me?​
yan [13]

Answer:

-3, -4, -4, 0, 16, 64, 192.

Step-by-step explanation:

I don't know for sure if this is correct, but when i did it theses are the answers i got. You do y=8*2^x. Meaning you substitute the x for the x values such as -3, -2, and -1.  

Also if you have one there's a setting you can go to on an actual calculator and type in this on a Y/X chart. I didn't use one this time because i don't have one, but thought you'd find that information useful.
