the function f(x)= sqrt x is translated left 5 units and up 3 units to create the function g(x). what is the domain of g(x)?
Zinaida [17]

Answer:

x ≥ -5

Step-by-step explanation:

If we have a translation to left c units, we write " x + c " in the function, and

If we have a translation to right c units, we write " x - c" in the function

If we have vertical translation up b units, we "add b to the function", and

If we have vertical translation down b units, we "subtract b to the function"

The parent function is  f(x)=\sqrt{x}

Since translation left 5 units and up 3 units, we can write:

f(x)=\sqrt{x+5} + 3

The domain is affected by the square root sign and we know the number under the square root CANNOT be negative, so we can say:

x + 5 ≥ 0

x ≥ -5

This is the domain.

Simplify by finding the product of the polynomials below. Then Identify the degree of your answer. When typing your answer use t
Alona [7]

Given:

(9a^2-4)(9a^2+4)

The shown represents the difference between the squares

So, the product of the polynomials will be as follows:

\begin{gathered} (9a^2-4)(9a^2+4) \\ =(9a^2)^2-(4)^2 \\ =81a^4-16 \end{gathered}

So, the answer will be:

This simplifies to:

81a^4-16

The degree of our simplified answer is 4

How many whole cubecan be cut from a cuboid measuring 33 cm by 29 CM by 18 cm
xz_007 [3.2K]
Volume = length x width x height
Volume = 33 x 29 x 18
             = 17,226
Number of whole cubes formed by the defined volume = 17,226/3
                                                                                       = 5742 cubes

Which expression represents the composition f(g(h(x))) for the functions below? f(x) = 2x + 1 g(x) = 4x2 h(x) = x2
ANEK [815]
The correct answer is option (b)

Given:
f(x) = 2x + 1
g(x) = 4x^2
h(x) = x^2
Now, g(h(x)) = 4 (x^2)^2 = 4x^4
Now, f(g(h(x))) = 2(4x^4) +1 = 8x^4 + 1

Thus, option b is correct answer
