Find the average rate of change for the given function from x = -1 to x = 4 ( i would like someone to explain this for me to)

The average r. of c. for the given fn. on [-1, 4] is -2.

Step-by-step explanation:

The graph of this function tells us that it's a linear function.  The rate of change of a linear function is constant and is equal to the slope of the line.  So we need to determine the slope from the graph:

As we move from (0, 3) to (2, -1) x increases by 2 and y decreases by 4.  Thus, the slope is m = rise / run = -4/2, or -2.  The slope is m = -2.  This is also the rate of change of this function for any interval, including the interval [-1, 4].

step-by-step explanation:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
