What isthe vertical line test​

Mathematics

Irina-Kira [14]3 years ago

The vertical line test is a visual way to determine if a curve is a graph of a function or not.

A function can only have one output, y, for each unique input, x. If a vertical line intersects a curve on an xy-plane more than once then for one value of x the curve has more than one value of y, and so, the curve does not represent a function.

If all vertical lines intersect a curve at most once then the curve represents a function.

Oxana [17]
X + y = 120000
0.15x - 0.10y = 5500

Multiply both sides of bottom by 100 to remove decimals

x + y = 120000
15x - 10y = 550000

Multiply both sides of top by 10

10x + 10y = 1200000
15x - 10y = 550000

Add the two

25x = 1750000
x = 70000
He paid $70,000 for the property that made a profit, and paid $50,000 for the property that lost value.

What does it mean to analyze a graph and write a story for a function? Explain and give an example.
Evgesh-ka [11]

Answer:

Step-by-step explanation:

To analyse a graph you are meant to determine a general trend, relating the results of an experiment to the hypothesis as well as to form. For example you look at all the values in a line graph and you are yo predict one you are to find its common increase or decrease.

If all possible vertical lines will only cross the relation in one place, then the relation is a function.This works because if a vertical line crosses a relation in more than one place it means that there must be two y values corresponding to one x value in that relation.

What is the slope of -y=-x+6
Katarina [22]

<u>Answer:</u>

  • m = 1
  • b = -6

<u>Step-by-step explanation:</u>

We know that:

  • -y = -x + 6
  • y = mx + b

First, we need to change the 'y' sign.

  • => -y = -x + 6
  • => y = x - 6

Now, let's compare both of the equations to find slope.

  • => (y = x - 6) = (y = mx + b)

We can see that the slope is 1 and the y-intercept is -6.

<u>Conclusion:</u>

Therefore:

  • m = 1
  • b = -6

Hoped this helped.

Find the composite function (please help)
anastassius [24]

Answer:

(f o h)(x) = -10x + 32

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

  • Composite Functions

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 2x³ + 8

h(x) = ∛(12 - 5x)

(f o h)(x) is f(h(x))

<u>Step 2: Find Composite Function</u>

  1. Substitute:                         (f o h)(x) = 2(∛(12 - 5x))³ + 8
  2. Evaluate:                            (f o h)(x) = 2(12 - 5x) + 8
  3. Distribute 2:                       (f o h)(x) = 24 - 10x + 8
  4. Combine like terms:         (f o h)(x) = -10x + 32

And we have our final answer!
