If x represents the time the average rate of change of function in the first two seconds is

Rate of change of function in first 2 seconds is units per second.

Step-by-step explanation:

Average rate of change of a function is its gradient/slope (m)

Gradient or the rate of change can be calculated by the following equation,

Here refers to a certain y axis value of the line drawn and is the x value that corresponds to that y value. and operates with same logic.

Lets pick a y value from the graph,

= 100

So the x value corresponding to that () would be 2

Lets pick another y value from the graph.

= 50

So the x value corresponding to that () would be 0

So by substituting to the equation for gradient or the rate of change,

=

=

=

The graph is a linear graph so the rate of change of function is the same in every position.

Therefore the Rate of change of function in first 2 seconds is units per second.

step-by-step explanation:

if x = 2 you have to find x to finish the problem
