what are the missing values, and what is the equation for the table

For this problem, you need to plug in 2 "coordinates", ex (1,16), and (0,__). You would need to find the slope, which would be y2-y1/x2-x1 (find two "coordinates" and then put it in, order doesn't matter.)

Hope this helps!

Answer:

see attached for table values
exponential equation: y = 8·2^x; linear equation: y = 60x -44

Step-by-step explanation:

Two points are not sufficient to define a graph, so the equation could be anything that gives the listed values.

We note that the given y-values are powers of 2. Specifically, they are 2^4 and 2^8. These powers differ by 4, just as the corresponding x-values differ by 4. This suggests an exponential equation might be good fit:

y = 2^(x+3)

Simplified, this is ...

y = 8·2^x . . . . . exponential equation for table values

Alternate solution

Often, when only two points are given, a linear function is indicated. We can use the two given points in the 2-point form of the equation for a line to find what the linear equation might be.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (256 -16)/(5 -1)(x -1) +16 . . . . with values filled in

y = 240/4(x -1) +16 . . . . . . . . . . . find the ratio

y = 60x -60 +16 . . . . . . . . . . . . . eliminate parentheses

y = 60x -44 . . . . . linear equation for table values
