consider the function represented by the equation 16b = 4r - 12. write the equation in function notation, where b is the indepen
katovenus [111]

When you write a function in the form y=f(x), y is the dependent variable, and x is the independent variable.

So, if b is the independent variable, it means that we have to solve the expression for r.

To do so, we perform the following steps: start with

16b = 4r - 12

Add 12 to both sides

16b+12 = 4r

Divide both sides by 4:

4b+3 = r

So, we wrote the expression in the form r = f(b) = 4b+3, which means that r is the dependent variable and b is the independent variable, as requested.
