Amountain climber ascends a mountain to its peak. the peak is 12,740 ft above sea level. the climber then descends 200 ft to meet a fellow climber. find the climber’s elevation above sea level after meeting the other climber.

answer: the value of x is 7cm

step-by-step explanation:

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.
