Need ! 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

r(b) = 4b +3

Step-by-step 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

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.

step-by-step explanation:

b and c
