What are the steps to a graph a quadratic function

Mathematics
1 answer:
Illusion [34]9 months 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:

10. A cylindrical can has a base with a diameter of 6 cm. Its height measures 5 cm. What is the total surface area of the can?
eduard

Answer:

  • Total surface area of cylinderal can is 150.8 cm²

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

Given that a cylinderal can has base with a diameter of 6 cm and its height measures 5 cm.

So,

Radius = Diameter/2 = 6/2 = 3 cm

We know that,

  • TSA of cylinder = 2πr(h + r)

Substituting required values:

➝ TSA = 2 × 22/7 × 3(5 + 3)

➝ TSA = 44/ 7 × 3 × 8

➝ TSA = 1056/7

➝ TSA = 150.8 cm²

Hence,

  • <u>Total </u><u>surface </u><u>area </u><u>of </u><u>cylinderal</u><u> </u><u>can </u><u>is </u><u>1</u><u>5</u><u>0</u><u>.</u><u>8</u><u> </u><u>cm²</u>
