State the definition of a function?

1 answer:

6 0

A function is a special relationship where each input has a single output.

It is often written as "f(x)" where x is the input value.

Example: f(x) = x/2 ("f of x is x divided by 2") is a function, because each input "x" has a single output "x/2":
• f(2) = 1
• f(16) = 8
• f(−10) = −5

Which graph does NOT represent y as a function of x?

alukav5142 [94]

Answer:

The first one ( vertical line )

Step-by-step explanation:

The graph is not a function because it doesn't pass the vertical line test.

The vertical line test is a test which uses a vertical line to make sure the graph does not have any mutual y values for distinct x values.

Also, the equation for the line is x=3 which doesn't represent y as a function of x.

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(3, -2), B(6, -2), C(6, 5),

aev [14]

First you want to find the length and width of the rectangle using the distance formula:

d=√(x2-x1)²+(y2-y1)²

AB=√(6-3)²+ (-2 - -2)²
AB=√3² + 0
AB=√9
AB=3

BC=<span>√(6-6)²+ (5 - -2)²
BC=</span>√0 + 7²
BC=√49
BC=7

We can find the area by multiplying these two distances together:

A=(3)(7)
A=21 units²

A square piece of plastic has a perimeter of 8 cm. how long is each side of the piece of plastic?

Aleksandr-060686 [28]

Answer:

Step-by-step explanation:

Since it is a square, all four sides are equal and its perimeter is just

P=4s, so if P=8 then

4s=8, dividing each side by 4 we get

s=2

So each side of the plastic square is 2 centimeters.
