First we need to find f(2) and f(5), which are 5 and 11 respectively; all you have to do is plug in 2 and 5.
Then, we use the following formula:
(f(b)-f(a))/(b-a),
where b and a are the largest and smallest x values respectively.
Finally, we plug our values in:
(11-5)/(5-2)=6/3=2
In fact, the average rate of change of any linear function is just the coefficient of the x term. Hope this helped!
75.99 (tenths)
75.991 (hundredths)
75.9913 (thousandths)
I think it is 6 7/8 since 2 3/4 x 2 1/2 =6 7/8
The y intercept is (0,3). The x intercept is (-9,0).
Hope this helps!
4(4a 7 ) 3(2a 5) = 4 ( 4 x 5 x 7 ) x 3 ( 2 x 5 x 5 ) = 560 x 150 = 84000
