A polynomial with integer coefficients is of the form \[x^4 + a_3 x^3 + a_2 x^2 + a_1 x + 18.\]You are told that the integer $r$

Pepsi [2]

Answer:-2 and 2

Step-by-step explanation:

Since the polynomial given [x^4 + a_3 x^3 + a_2 x^2 + a_1 x + 18.\] is divisible by (x - r)^2, this means that (x - r)^2 is a factor of the polynomial just like 4 is divisible by 2, we say 2 is a factor.

Since (x - r)^2 is a factor, we equate the factor to zero in order to get the 'x' variable.

(x - r)^2 =0

Taking square root of both sides gives x-r =0 i.e x=r

Substituting x=r into the polynomial to get 'r' we have r^4 + a_3 r^3 + a_2 r^2 + a_1r + 18=0.

Let a be 1 since the coefficients are integers

We then have Answer:

Taking square root of both sides gives x-r =0 i.e x=r

Substituting x=r into the polynomial to get 'r' we have r^4 + r^3 + r^2 + r + 18=0.

Factorizing this, possible value of r will be -2 and 2

I don't get this !!!!!!!11

Hello.

So, you should already know that to find the inverse of a function you switch x and y and solve.

For f(x) = x² + 3, it's domain is all real numbers, and the range is y ≥ 3.

The inverse of f(x), it is $f^{-1}$ , and the equation is $f^{-1}$ = ±√(x - 3). It's domain is x ≥ 3, and the range is all real numbers.

There are many unique characteristics about inverses, like the values of x and y are switched, it's reflected on the line y = x, and the domain and range is switched.

So your final answer is c. f(x) domain: all real numbers, range: y ≥ 3
$f^{-1}$ domain: x ≥ 3, domain: all real numbers.

Hopefully it makes sense! :)
