A) Find a polynomial, which, when added to the polynomial 5x2–3x–9, is equivalent to: 18

VMariaS [17]

Answer:

a) $-5x^{2}+3x+27$

b) $-5x^{2}+3x+9$

Step-by-step explanation:

a) Let the required polynomial be p(x).

We have the relation, $5x^{2}-3x-9$ + p(x) = 18

i.e. p(x) = 18 $-5x^{2}+3x+9$

i.e. p(x) = $-5x^{2}+3x+27$

b) Let the required polynomial be q(x).

We have the relation, $5x^{2}-3x-9$ + q(x) = 0

i.e. q(x) = 0 $-5x^{2}+3x+9$

i.e. q(x) = $-5x^{2}+3x+9$

The domain of f(x) is the set of all real values except 7, and the domain of g(x) is the set of all real values except –3. Which

bija089 [108]

Answer:

The set of all real values except 7

Step-by-step explanation:

We are given that,

Domain of the function f(x) is 'the set of all real values except 7'.

Domain of the function g(x) is 'the set of all real values except -3'.

It is required to find the domain of $(g\circ f)(x)$ .

Now, we know that,

The composition $(g\circ f)(x)$ of functions $f(x)$ and $g(x)$ will be defined where the function $f(x)$ is defined.

Since, the domain of f(x) is 'the set of all real values except 7'.

Thus, the domain of $(g\circ f)(x)$ is also 'the set of all real values except 7'.
