Help is this graph a function?

Mathematics
1 answer:
ale4655 [162]2 years ago

Since each value of x is mapped to only one value of y, this graph represents a function.

<h3>When does a graph represent a function?</h3>

A graph represents a function when it has no vertically aligned points, that is, if <u>each value of x is mapped to only one value of y</u>.

This is one example of a graph without vertically aligned points, as if we traced vertical lines on the graph, they would cross the function only once, hence this graph represents a function.

A similar problem, in which we verify if a graph represents a function, is given at brainly.com/question/12463448

If the discriminant of a quadratic equation is equal to -9, which statement describes the roots?
Mice21 [21]

ANSWER

No real roots.

The roots are complex or imaginary.

EXPLANATION

The quadratic equation

a {x}^{2}  + bx + c = 0

has discriminant,

D =  {b}^{2}  - 4ac

If the discriminant is less than zero , then the quadratic equation has no real roots.

The given discriminant is -9.

Since -9 is less than zero, it means the quadratic equation has complex or imaginary roots.

What is the slope of the line with the following equation?<br><br> <img src="https://tex.z-dn.net/?f=2x%2B3y%3D2" id="TexFormula
KengaRu [80]

QUESTION

Your equation is 2x+3y=2 and you need to find the slope.

EXPLANATION

There are many ways to find the slope with an equation like this. I'm going to change the equation into slope-intercept form.

Slope-intercept form is formatted like this:

y=mx+b

m represents the slope. The first thing you need to do is leave 3y alone to change the equation into slope-intercept form. That means you need to subtract 2x from both sides.

2x+3y=2 \rightarrow 3y=2-2x\ or\ 3y=-2x-2

The next thing you need to do is leave y alone, just like the slope-intercept form example. To leave y alone, you need to divide 3y by 3.

\frac{3y}{3}=\frac{-2x-2}{3} \\ \\ y=-\frac{2}{3}x-\frac{2}{3}

Now the equation has been changed to slope-intercept form. In the equation, m has been replaced by -\frac{2}{3}, which means that is your answer.

Answer: -\frac{2}{3}

13. What is the surface area of the rectangular solid below using its net?
loris [4]

<u><em>Answer:</em></u>

108 square units

<h3><u><em>Step-by-step explanation:</em></u></h3>

3 x 4 = 12

3 x 4 = 12

6 x 3 = 18

6 x 3 = 18

6 x 4 = 24

6 x 4 = 24

24(2) + 18(2) + 12(2) = 108 square units

Therefore, the surface area of the rectangular solid below using its net is <u>108 square units</u>
