Question

Consider the function represented by the equation 6q=3s-9. Write the equation in function notation, where q is the independent variable

Answer 1

independent variable means solve for the other variable in terms of that indepenent variable

so solve for s in terms of q

6q=3s-9
add 9 to both sides
6q+9=3s
divide bot sides by 3
2q+3=s
s=2q+3
so as a function
s(q)=2q+3
or
f(q)=2q+3

Answer 2

f(q)=2q+3... This is the equation in a function notation with q as the independent variable
