Answer:

The y-intercept is (0,1)

Step-by-step explanation:

So, first you need to find the equation! Point slope form is (y-y1)=m(x-x1).

Plug the numbers in and you get (y-7)=3(x-2). Now, the y intercept is where x=0, so plug in zero for x.

y-7=3(0-2)

y-7=3(-2)

y-7= -6.

-6+7= 1, so y=1

The ordered pair is then (0,1). Hope this was useful :)

The output of a function or relation, or the set of y-values that a graph is defined for, is called the ___.

Andre45 [30]

Answer:

Range

Step-by-step explanation:

The range of a graph tells you <u>all of the possible y-values</u> for it.

There is also the domain, which tells you all of the possible x-values.

For example, if you have this relation, that only has these points:

(1, 2) (2, 4) (3, 6)

Then the range is {2, 4, 6}. This means the "y" can ONLY be the numbers stated here.

The domain would be {1, 2, 3}.

Answer:

$\frac{1}{4x}$

Step-by-step explanation:

The negative exponential can be represented with the help of fractions. By this way, we also make the negative exponential disappear. For example, we can write:

$a^{-1} = \frac{1}{a}$

The explanation is this:

Since $a^{0}=1, \frac{1}{a}=\frac{a^{0} }{a^{1} } = a^{0-1} =a^{-1}$

According to this definition, we can simplify our problem in the following way:

$(4x)^{-1} = \frac{1}{(4x)^{1} } = \frac{1}{4x}$
