So the "back" of the arrow is on/above -20.

The arrow points to -12.

You added something to -20 to get to -12.

So the first number is -20. You added ? to get -12. -12 is the last number / the answer to the equation.

So the equation from what you have so far is -20 + ? = -12

You need to isolate the ? so that you know what it is.

So to get rid of the -20 (make it 0), you have to add 20. -20 plus 20 equals 0, which basically means it is gone. You also have to add 20 to -12. 20 plus -12 equals 8.

Now the equation is ? = 8.

So you know that the second number is 8.

The equation makes sense; -20 + 8 = -12.

One x-intercept of the graph of the of the cubic function f(x) = x^3 – 2x^2 – 111x – 108 is –9.
katrin2010 [14]

Answer:

The zeros of the given function are -9,-1 and 12.

Step-by-step explanation:

The given function is

f(x)=x^3-2x^2-111x-108

It is given that the x-intercept of the graph is -9, therefore -9 is a zero of the function.

Since -9 is the zero of the function, therefore (x+9) is a factor of f(x). Use synthetics method or long division method to divide the function by (x+9).

f(x)=(x+9)(x^2-11x-12)=0

f(x)=(x+9)(x^2-12x+x-12)=0

f(x)=(x+9)(x(x-12)+(x-12))=0

f(x)=(x+9)(x-12)(x+1)=0

Use zero product property and quote each factor equal to 0.

x=-9,-1,12

Therefore zeros of the given function are -9,-1 and 12.
