How many x intercepts appear on the graph of this polynomial function? fx)=x*-x+x²-x 1 x intercept 2 x intercepts 3 x intercepts 4x intercepts o

0

Step-by-step explanation:

1

Step-by-step explanation:

Here f(x) = x^2 - 2x - 5, which at x - -5 is 25 +10 - 5 = 30 and at x = 6 is 19.

The average value of a function f(x) over an interval [a, b] is

                  f(b) - f(a)

ave. val. =

                     b - a

which in this particular case is

                     19 - 30

ave. val. = = -11/11 = 1

                     6 - (-5)

The average value of this function f(x) = x^2 - 2x - 5 on [-5, 6] is 1.
