Answer:

The domain of a function is the set of all possible inputs for the function.

Step-by-step explanation:the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.

How would the domain and range of the function y = one-fourth x minus 6 be determined? Explain.

Liono4ka [1.6K]

Answer:

Domain = ( -∞ , ∞ )

Range = ( ∞ , ∞ )

Step-by-step explanation:

A function is given to us and we need to find the domain and range of the given function .

The function :-

$\rm \implies y = \dfrac{1}{4}x - 6$

Definitions :-

Range :- The range is the set of all valid y values .
Domain :- All real numbers except where the expression is undefined.

In this case, there is no real number that makes the expression undefined. Therefore the domain will be :-

Domain :-

$\rm Domain = ( -\infty , \infty )$

$\rm Domain = \{ x | x \in \mathbb{R} \}$

Range :-

$\rm Range = ( -\infty , \infty )$

$\rm Range = \{ y | y \in \mathbb{R}\}$

Joe left the hospital at the same time as Eugene. They drove in opposite directions. Eugene drove at a speed of 70 km/h. After t

Gala2k [10]

If Joe and Eugene are travelling in opposite directions, their total distance is 360 km.

Eugene's speed = 70 km/hour

Let Joe's speed be = x

They each travel for 3 hours, so time = 3 hours

Distance = speed * time

$360=70(3)+x(3)$

$360=210+3x$

$3x=150$

$x=50$

Hence, Joe's speed is 50 km per hour.

Which expression represents the volume of the prism?

Tamiku [17]

Answer:

x³-2x² = x2(x – 2) cubic units

Step-by-step explanation:

The volume of a prism is found by multiplying the base area by the height. The base area is a parallelogram and so the area is x*(x-2) = x² -2x.

Multiply this area by the height x.

V = x(x² - 2x) = x³-2x²

This is the same as x2(x – 2) cubic units.
