Answer:
x is the input, or independent variable and f(x) is the output, or dependent variable or quantity. f(2) represents the output (y-value) when x = 2. The value of f(2) is 2.
Step-by-step explanation:
If the values of a variable depends on the other variable, then it called dependent variable.
If the value of a variable does not depend on the other, then it is called independent variable.
If a function is f(x)=x, then x is an independent variable and f(x) is a dependent variable.
The given function is
Here, x is the input, or independent variable and f(x) is the output, or dependent variable or quantity.
The notation f(a) represents the output (y-value) when x = a. So, f(2) represents the output (y-value) when x = 2.
Substitute x=2 in the given function.
The value of f(2) is 2.
Answer:
8y= -16
7x= -7
so 1y =-2 meaning 8y is -16 + 7x and if 1x is -1 then it is -7 altogether so if you add -16 and -7 you get -23

Answer:
C 33.52 cm³
Step-by-step explanation:
Here, we have Radius(r)=2(Given)
Volume = 4/3 πr³
= 4/3 · 22/7 · 2³
= 33.5238
Round to the nearest tenth:
C 33.52 cm³
