Answer:

Step-by-step explanation:

Given a polynomial f(x) divided by (x + h) then the remainder is f(- h)

Here f(x) is divided by (x + 4), thus remainder is calculated as

f(- 4) = (- 4)³ + 5(- 4)² - 7(- 4)

= - 64 + 5(16) + 28

= - 64 + 80 + 28 = 44 ← Remainder

They are not
It goes from
0/0 1/3 2/5 3/6(or 1/2) which are not the same. This makes them not proportional to one another. (I think)

Check all solutions to the equation. If there are no solutions, check "None."x2=0A. 1B. -1C.0D. 10E. 4E None

The given equation is,

$\begin{gathered} x^2=0 \\ x=0 \end{gathered}$

Thus, option (C) is the correct solution.

Domain and range of the function and it’s inverse

sineoko [7]

Answer:

B (second table in list)

Step-by-step explanation:

The function is a quadratic with vertex and y-intercept at (0,-2). The parabola opens up meaning only y - values above -2 are a part of the function. Since range is the set of all y values, then the range is $y\geq -2$ .

The domain is not restricted and it is all real numbers.

The inverse of the function is where x and y are switched. So the range becomes the domain and vice verse.

This means the domain of the inverse is $x\geq -2$ and the range of the inverse is all real numbers.
