Question 4 • Mathematics I

Consider the function represented by the equation y minus 6x minus 9 is equal to 0 Which answer shows the equation written in function notation with x as the independent variable?

Answer
A
f of y is equal to 1 sixth y plus 3 halves
B
f of x is equal to 6 x plus 9
C
f of y is equal to 6 y plus 9
D
f of x is equal to 1 sixth x plus 3 halves

Explanation

Rearrange y − 6x − 9 = 0 by adding 6x and 9 to both sides, giving y = 6x + 9. Since x is the independent variable, write y as f(x), so the function is f(x) = 6x + 9, choice A.
