So we got the function of the graph f(x) = 2^x + 1 what you will need to do first is find the y-coordinates corresponding to x=1 and x=3 which can be found by substituting into the function. After that we can find the average rate of change using y2-y1/x2-x1.
f(1)=2^1+1 which would be equal to 3
1,3
f(3)=2^3+1 which would be equal to 9
3,9
9-3/3-1=6/2
6/2=3
The average rate of change is 3.
Answer:
It is 1/3

can i have brainly?
Answer: ik nothing of basketball sorry
(a) - 5
since y varies inversely as x then k = yx ( k is the constant of variation )
using y = 5 when x = - 1, then k = 5 × - 1 = - 5
<span>2 inches = 25 miles
?,,,,,,,,,,,,,,,</span><span>60 miles
</span>
60 x 2 / 25 = 4.8 inches
<span>1/4 = 0.25 inches
0.25 x 25 / 2 = 3.125 miles
