Khalid wrote the sequence below.
x-1, -2x+2, 4x-4, -8x+8
which formula can be used to find the 10th term of the sequence?
a. a10=(x-1)*(-2)^10-1
b. a10=(x-1)^10-1
c. a10=(x-1)*(2)^10-1
d. a10=(x-1)*(-2)^10

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
