So in the graph shown here, notice that the x terms seem to be increasing in both a positive and negative direction and there seems to be no limit to how large or how small the x terms can get. So the x terms can be all positive and negative numbers, including decimals and fractions.

In other words, the x terms can be All Real Numbers.

So the domain is equal to the set of all real numbers or R.

The range is the set of all the y terms.

Notice that all the y terms are less than or equal to 9.

So the range is {y: y ≤ 9}.

A local gym charges a $100 initial membership fee and $19 for each month you stay a member. What are the x and y intercepts?

Answer:

y-intercept = 100
x- intercept = -5.26

Step-by-step explanation:

$100 initial membership fee
$19 monthly fee

Function of relationship:

y = 19x + 100

y- intercept:

x =0 ⇒ y = 19*0 + 100 ⇒ y = 100

x - intercept:

y = 0 ⇒ 0 = 19x + 100 ⇒ 19x = -100 ⇒ x = -100/19 ⇒ x = -5.26
