Explain why a graph that fails the vertical-line test does not represent a function. Be sure to use the definition of a function

ArbitrLikvidat [17]2 years ago

Explanation:

A function is a relationship where any one x-value/input only has <u>one </u>corresponding y-value/output. (note: a y-value can have multiple x-values).

> This can be called "assigning one y-value to every x element".

The vertical line test places a line that would connect all y-values of an x-value (that is, if it were to have multiple y-values). If multiple points can be found along the vertical line, it is, therefore, by the definition of a function, not a function. (Because an x-value will have more than one y-value).

So, a graph that fails the vertical-line test does not represent a function because an x-value will correspond with more than one y-value.

hope this helps!!

The campers in cabin A walked 1/4 of the way to otter ridge (13 miles) How many miles did they walk?
shusha [124]
The question demands that we find a fraction of a given quantity.

The 'of ' means multiplication.

So the total distance of the journey was

13 \: miles

But they walked ¼ of the whole journey. We are supposed to find

\frac{1}{4} \: of \: 13 \: miles
\\= \frac{1}{4} \times 13 \: miles

= \frac{13}{4} \: miles

= 3.25\: miles

Hence they walked 3.25 miles.

Write the equation of the graphed in NO SPACES ALL LOWERCASE<br> Help !!
cupoosta [38]

Answer:

The equation of the graphed line is:

  • y = 2

Step-by-step explanation:

From the graph, it is clear that the line is a horizontal line at y = 2.

We know that a horizontal line has a slope of 0 because the value of y does not change no matter what the value of x we put in.

In other words, the equation of the horizontal line would always get the form:

y = k

where k is the y-intercept of the line.

Determining the y-intercept of the line:

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 2

Thus, the y-intercept k = 2

Thus, if we substitute the y-intercept k = 2 in the equation y = k, we get the equation

y = 2

Therefore, the equation of the graphed line is:

  • y = 2
