Find the average rate of change for the given function drom x=1 to x=2

An object is accelerating at a constant rate. its velocity in feet per second as a function of time in seconds can be modeled by the linear function v(t) = 2.5t. what does the dependent variable represent for this function? a) acceleration b) distance c) slope d) velocity

F(x)=3(1.54)^x whats this how do you do it
