Why use f(x) instead of y?

The notation "f(x)" is exactly the same thing as "y"

Step-by-step explanation:

The effect of using f(x) instead of y is that it allows us to talk about f.

If we have an equation relating X to Y then that's a relationship between rwo nimbers.

For example if you have that y=

...then that means that X and Y are some numbers obeying that equation

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
