Answer:

The average rate of change from x=0 to x=1 for f(x) is 0.

Explanation:

We are given the function
f(x)=-3x^(4)-x^(3)+3x^(2)+x+3.

Now, the rate average rate of change of a function from
y=x_(1) to
y=x_(2) is given by
(f(x_(2))-f(x_(1)))/(x_(2)-x_(1)).

As, we need the rate of change from x = 0 to x = 1.

So, we will find the values of f(0) and f(1).

i.e.
f(0)=-3*0^(4)-0^(3)+3*0^(2)+0+3 i.e. f(0) = 3

and
f(1)=-3*1^(4)-1^(3)+3*1^(2)+1+3 i.e.
f(1)=-3-1+3+1+3 i.e. f(1) = 3

Thus, the rate of change from x=0 to x=1 is
(f(1)-f(0))/(1-0) i.e.
(3-3)/(1-0) i.e. 0

Hence, the average rate of change from x=0 to x=1 for f(x) is 0.
