Question

NEED HELP PLEASE!

Consider the function represented by the equation 16b = 4r - 12. write the equation in function notation, where b is the independent variable. Must show work for full credit

Answer 1

r(b) = 4b +3

Explanation:

There are only two variables and the one that is not b is r. So, this amounts to solving for r. Divide the given equation by the coefficient of r:

... 4b = r -3

Add the constant:

... 4b +3 = r

Express in function notation.

... r(b) = 4b +3
