Answer:

Domain is all the possible X values on a graph

Range are all the possible Y values on a graph

Step-by-step explanation:

Example- If given a graph where on the X line goes from 0-10 and Y goes from 0-30 the domain would be all real numbers 0-10 and range would be all real numbers 0-21

Please help ASAP!!!!!!!!!! Which expression is equivalent to the following complex fraction? 1 + StartFraction 1 Over y EndFract

sveticcg [70]

Answer:

$(B)\dfrac{y+1}{y-1}$

Step-by-step explanation:

We are to find an equivalent expression for:

$\dfrac{1+\frac{1}{y} }{1-\frac{1}{y}}$

Step 1: Combine the terms in the numerator into one fraction. Do the same for the denominator.

$=\dfrac{\frac{y+1}{y} }{\frac{y-1}{y}}$

Step 2: Write on a straight line and simplify

$=\dfrac{y+1}{y} \div \dfrac{y-1}{y}\\=\dfrac{y+1}{y} \times \dfrac{y}{y-1}\\=\dfrac{y+1}{y-1}$

The correct option is B.

The graph represents function 1 and the equation represents function 2:

Lemur [1.5K]

If the function 1 in graph is a horizontal line y=3 then it has zero rate of change because y is same along the x axis.

Function 2 has rate of change of 2.

Y=mx+c m represents rate of change

Use the graph to determine the domain and range of the relation, and whether the relation is a function

MAVERICK [17]

domain is correct for b and c

the graph is a function because each value of x has only one y value

hence answer is B
