The slope
of a line is a number that
measures its "steepness", usually
denoted by the letter m. It is the
change in y for a unit change in x
along the line.
In linear models there is a constant additve rate of change. For example, in the equation y = mx + b, m is the constanta additivie rate of change.
In exponential models there is a constant multiplicative rate of change.
The function of the graph seems of the exponential type, so we can expect a constant multiplicative exponential rate.
We can test that using several pair of points.
The multiplicative rate of change is calcualted in this way:
[f(a) / f(b) ] / (a - b)
Use the points given in the graph: (2, 12.5) , (1, 5) , (0, 2) , (-1, 0.8)
[12.5 / 5] / (2 - 1) = 2.5
[5 / 2] / (1 - 0) = 2.5
[2 / 0.8] / (0 - (-1) ) = 2.5
Then, do doubt, the answer is 2.5
(f/g)(8)=f(8)/g(8)
find f(8) and g(8) to mke it easier
f(8)=3-(8)=3-2(8)=3-16=-13
g(8)=1/(5+8)=1/13
so (f/g)(8)=-13/(1/13)=-13*13=-169
answer is -169
