The dimensions of various-sized mirrors are created using the expression 0.5x – 2 for the width and 2x + 2 for the length. The function A(x) = x2 – 3x – 4 represents the area of the mirrors. The maximum length of the mirrors is 52 centimeters.

How do the mathematical domain and reasonable domain compare?

a.) mathematical: {x E R} reasonable: {x > 0}

b.) mathematical: {x E R} reasonable: {x > 4}

c.) mathematical: {x > 1.5} reasonable: {x > 0}

d.) mathematical: {x > 1.5} reasonable: {x > 4}
