Answer:
For the function
the average rate change from x is equal 1 to x is equal 2 is 4 .
Step-by-step explanation:
A function is given f(x)=4x-3.
It is required to find the average rate change of the function from x is 1 to x is 2 . simplify.
Step 1 of 2
A function f(x)=4 x-3 is given.
Determine the function
by putting the value of x=1 in the given function.

Determine the function
by putting the value of x is 2 in the given function.

Step 2 of 2
According to the formula of average rate change of the equation 
Substitute the value of
with,
with
with 2 and
with 1 .

Recall that the derivative of a constant is 0.
