15. determine the zeros for and the end behavior of f(x) = x(x - 4)(x + 2)

Explanation:

The zeros of a function are all the values of x for which f (x) = 0.

Therefore to find the zeros of the function I must equal f(x) to zero and solve for x.

We have the multiplication of 3 factors x, (x-4) and (x + 2)

Then the function will be equal to zero when one of the factors is equal to zero, that is:

Note that is a cubic function of positive principal coefficient, the graph starts from and cuts to the x-axis at , then decreases and cuts by second once to the x-axis at , it finally cuts the x-axis for the third time at and then tends to

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
