Question

10 TIME REMAINING 38:46 Consider the function represented by the equation y minus 6 x minus 9 = 0. Which answer shows the equation written in function notation with x as the independent variable? f of x = 6 x + 9 f of x = one-sixth x + three-halves f of y = 6 y + 9 f of y = one-sixth y + three-halves

Answer 1

f of x = 6 x + 9

Explanation:

Answer 2

f of x = 6 x + 9

Explanation:

Given the equation :

y minus 6 x minus 9 = 0

y - 6x - 9 = 0

Write the equation in function notation with x as the independent variable.

y - 6x - 9 = 0

Make y the subject of the formula;

Move - 6x - 9 to the Right hand side

y = 6x + 9 (sign changes)

Expressing y as a function of x;

f(x) will be equal to y ;

Mathematically ;

f(x) = y

Hence ;

f(x) = 6x + 9

From the general linear equation :

mx + c = 6x + c

x = independent variable
