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

Explanation:

by : 6q=3s-9

calculate : s

6q+9 =3s-9+9 ....( added 9)

3s = 6q +3

s = 6/3 q +3/3 .... divid by 3)

s = 2 q +1 .....( equation in function notation where q is the independent variable )

Answer 2

`s=2q+3`

Explanation:

The given equation is
`6q=3s-9`

Here, q is dependent variable and s in independent variable because for different values of s, there will be different values of q. Hence, value of q depends on the value of s and hence q is dependent variable.

Now, we have yo find the equation, in which q is the independent variable. Thus, we solve the equation for s.

Add 9 to both sides of the equation

`6q+9=3s`

Now, divide both sides by 3

`s=2q+3`

Therefore, the equation is
`s=2q+3`
