Answer:

Graph B

Step-by-step explanation:

Remember that for a function to have an inverse, the function must be 1-to-1. The two functions must also be symmetrical about the line y=x, which is apparent in the second graph.

Answer:

Domain = All real numbers

Range = y ≥ 0

Step-by-step explanation:

As for the domain... you can substitute any value for x and get a mathematical response. Therefore... the domain is all real numbers

Because we are finding the absolute value of the entire function... we know that the final answer cannot be negative. (Don't forget that it can still be 0) Since y can only be positive... we define the Range as y ≥ 0

What is the solution to the system of equations graphed below? y = x - 2 y = 4x - 5

There are 3 available methods - Substitution , Elimination and Matrix.

The substitution method is used to eliminate one of the variables by replacement.

The elimination method is used for solving linear systems.

A Matrix is an array of numbers.

Lets use Substitution to solve this system.

$x-2=4x-5$

$-2=4x-5-x$

$-2=(4x-x)-5

 
$

$-2=3x-5$

$-2+5=3x$

$3=3x$

$3=3x / 3$

$x=1$

Now substitute $x=1$

$y=x-2$

$y=1-2

 
$

$y=-1

$

Hence - $x=1
 
y=-1$

Equation?

GarryVolchara [31]

25-5x=5(-x+5)
25-5x=-5x+25
-5x+5x= 25-25
0=0

So the answer will be A: there is no solution
