Question

A rectangle has an area of 24 cm2 Function f gives the length of the rectangle, in centimeters, when the width is w cm. Determine if each value, in centimeters, is a possible input of the function. A 0.5 B 48 C 0 D -6 E 3 0.5 0.5

Answer 1

Answer:

Input is the value of w and the function f = 24/w as length x breadth = area of rectangle

If w = 0.5, then f = 24/0.5 = 48cm. So, it is a possible input of the function.

If w = 48, then f = 24/48 = 0.5cm. So, it is a possible input of the function.

If w = 0, then f = 24/0 = 0cm. So, it is not a possible input of the function as it cannot be defined

If w = -6, then f = 24/-6= -4cm. So, it is not a possible input of the function as a length and width can't be negative

If w = 3, then f = 24/3 = 8cm. So, it is a possible input of the function.
