Answer:

x is greater than or equal to -7 but less than 9.

Step-by-step explanation:

Find the lowest and higest points on the graph.

Remember the domain is on the x - axis.

The lowest point on the graph is -7, but the dot is filled in so it must be equal to it.

The next step is that the graph is getting larger so it is greater than or equal to.

On the other side of the graph do the same but it is less than not equal because the dot is open.

Find a polynomial, which, when added to the polynomial 5x2–3x–9, is equivalent to: x2−5x+6

Bess [88]

The required polynomial is: $-4x^2-2x+15$

Step-by-step explanation:

Let P be the polynomial that has to be found

Given

One polynomial = $5x^2-3x-9$

Sum of both polynomials = $x^2-5x+6$

So,

$(5x^2-3x-9) + P = x^2-5x+6\\P = x^2-5x+6 - (5x^2-3x-9)\\P = x^2-5x+6-5x^2+3x+9\\P = x^2-5x^2-5x+3x+6+9\\P = -4x^2-2x+15$

Hence,

The required polynomial is: $-4x^2-2x+15$
