HELP ME PLS!!!! Which function represents a proportional relationship? A) f(x) = 3x 4 B) f(x) = 3 4x C) f(x) = 3x 4 + 3 4 D) f(x
Ganezh [65]

Answer:

Option B

f(x)=\frac{3}{4}x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem the only linear function that passes through the origin is

f(x)=\frac{3}{4}x

where

The constant of proportionality is k=3/4

Rashid [163]

Hello!


The number of tickets is dependent on age, so age is the independent variable.


Think of it as a y = mx equation. In this equation, x is the input, and y changes depending on the value of x inputted.


In this situation, y is the number of tickets, as y changes depending on the age x inputted. x is age, the independent variable.
