For the function
f(x) = 4^(x-1) +2
the average rate of change on the interval [1, 2] is found by computing
(f(2) - f(1))/(2 - 1)
= ((4^1+2) - (4^0+2)/1
= (6-3)
= 3
Answer: 104.77 $ without coupon
94.77 $ with coupon
Step-by-step explanation:
25.99 Times 3 = 77.97 $
5.65 times 2 = 11.3 $
77.97+11.3=89.27 $
89.27 + 15.50 = 104.77 $
104.77 - 10 dollars of coupon = 94.77 $
The greatest common factor of 81 and 135 is 27
The equation is y = -3/2
this is because the line crosses zero on the Y axis so there is no Y intercept
and to get the slope you just see how many units down & then right you need to get from the center point to the one more down
2x+5squared or 4x^2 + 20x + 25
