What are the steps to a graph a quadratic function

Mathematics
1 answer:
Illusion [34]1 year ago
6 0

You need 3 points to graph a quadratic function.

It is advisable that one of these points be the vertex, because the line of symmetry passes through it

Next, you need to find two other points that lie on the curve, replacing an x-value into the function and calculating the y-value. It is easier if these two points are at the same distance from the line of symmetry.

For example, if the quadratic function is y = (x - 4)² + 3, the vertex is located at (4, 3). Replacing with x = 3 into the equation, we get:

y = (3 - 4)² + 3

y = 1 + 3

y = 4

Replacing with x = 5 into the equation, we get:

y = (5 - 4)² + 3

y = 1 + 3

y = 4

Now, we need to connect the points (3, 4), (4, 3), and (5, 4) with a U shape, as follows:

Solve the following system of equations: 5x + y = 9 3x + 2y = 4 (−2, 5) (1, 4) (2, −1) (4, −4)
Mila [183]
Multiply first equation by 2:
10x + 2y = 18
Subtract the second equation from this so that the 2y terms cancel:
10x - 3x = 18 - 4
7x = 14
x = 2
Plug into first equation to find y:
5(2) + y = 9
10 + y = 9
y = -1
The answer is (2,-1)

23 20' 48" is the same as _____. <br><br> Round to the nearest hundredth of a degree.
pentagon [3]
23° 20' 48" in degrees

Minutes are 1/60 of a degree and seconds 1/60 of a minute.

Let's convert the 48" to minutes.
48/60 = 0.8

23° 20' 48" ⇒ 23° 20.8'

Let's convert the 20.8' to degrees.
20.8/60 ≈ 0.3466667

23° 20.8' ⇒ 23.35°

Identify the factors of x2 + 16y2.
BabaBlast [244]

The way to find the factores is by seeking the polonomial's roots, or zeros!

To find the roots, we set the polinomial equation to zero:

x^2+16y^2=0

Then we solve this equation:

x^2=-16y^2

This is only true, if x=y=0.
