What is the zeros and graph of f(x)=1/2(x+5)(x+1)(x-2)

When you write a polynomial in the form

You know that you have a polynomial of degree , which crosses the x axis at

So, in your case, you have a cubic which crosses the x axis at x=-5, x=-1 and x=2.

Moreover, since A=1/2 is positive, the end behaviour of the cubic is preserved, i.e.

This is all the information you need to sketch a first draft of the graph.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
