The location of the x-intercepts in the attached figure

Step-by-step explanation:

we know that

The x-intercepts of a function are the values of x when the value of the function is equal to zero

we have

f(x)=x^{3}-7x^{2}-26x+72

using a graphing tool

The x-intercepts are the points (-4,0). (2,0) and (9,0)

seraphim [82]

Answer:

Step-by-step explanation:

Goven the length of the field = 110m

Width = 80m

The length of the diagonal is expressed using the pythagoras theorem;

d² = l² + w²

d² = 110² + 80²

d² = 12100 + 6400

d² = 18500

d = √18500

d = 136.01

Hence the players have to run 136.01m diagonally
