Answer: The set of all real number.

Step-by-step explanation:

Domain of a function is a set of all possible value of independent variables.

Since, a polynomial is always defined for every real number,

⇒ The domain of a polynomial is always the set of all real number,

Here the given function is,

f(x) = 4x -16,

⇒ Which is a polynomial.

Hence, its domain is also the set of all real number.

Answer:

All real numbers

Step-by-step explanation:

We are given the following function and we are to determine its domain.

For a function, the domain is the set of all input values for which the function is defined to be true.

Here, we cannot have zero as the denominator and neither can we take the square root of a negative number. Therefore, the domain for this function will be all real numbers.

andriy [413]

Here is the equation: $x+(x+3)=11$ ⇒ $x+x+3=11$

You need to get "x" by itself so minus 3 from each side

$x+x+3-3=11-3$ ⇒ $x+x=8$ ⇒ $2x=8$

Divide 8 by 2

$8$ ÷ $2=4$

x=4

So each 4 is equivalent to 4

Lets check:

$4+(4+3)=11$ ⇒ $4+4+3=11$ ⇒ $11=11$

So that means that Marcus practiced the piano for 4 hours and Donnel practiced for 7

What transformation to the linear parent function, f(x) = x, gives the function g(x) = x + 8?

NeTakaya

Answer:

Shift 8 units up

Step-by-step explanation:

The given function is;

f(x)=x

and

g(x)=x+8

The function f(x) has its y-intercept at y=0.

The function g(x)=x+8 has its y-intercept at y=8

This implies that; the linear parent function f(x)=x is shifted up 8 units to obtain g(x)=x+8.
