Question

Consider the function represented by the equation

1/2j + 1/4k = 3 . Which shows the equation written in function notation with j as the independent variable?

f(j)= -2j+12
f(j)= -1/2j+6
f(k)= -2k+12
f(k)= -1/2k+6

Answer 1

1/2j + 1/4k = 3
1/4k = -1/2j + 3
k = - 2j + 12

f(j) = -2j + 12 <== function notation
