The table below represents the velocity of a car as a function of time: Time
(seconds)
X
15
Velocity
(m/s)
f(x)
45
22
66
87
29
36
108
The average rate of change of the function between x = 15 to x = 29 is
I
m/s2 and represents the car's acceleration

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

the answer to your question a or b but i am pretty sure it is b. i hope this : )
