Below are some examples of these types of functions: y = 2x + 1 y = 3x2 - 5x + 3 y = Sin(x) x2 + y2 = 4 y2 = x3 - Tan(x). These algebraic functions are all different and have different properties. It is often useful to have a visual way to look at these functions. Graphs provide such a tool.
Did you know: About 78% of the Average Human Brain Consists of Water. The human brain is the main part of the nervous system, coordinating all the functions of the body via electric impulses. The human brain hosts approximately 80 to 120 billion nerve cells and it is largely made of water. Water is of major importance to all living things; in some organisms, up to 90% of their body weight comes from water. Up to 60% of the human body is water, the brain is composed of 70% water, and the lungs are nearly 90% water. Lean muscle tissue contains about 75% water by weight, as is the brain; body fat contains 10% water and bone has 22% water.
Due to their low body fat and bone mass, infants are about 73% water. The body water content of men is about 60%, but since women have relatively more body fat and less skeletal muscle than men, theirs is about 50%. Total body water is a function of age, body mass, and body fat. Due to their low body fat and bone mass, infants are about 73% water. The body water content of men is about 60%, but since women have relatively more body fat and less skeletal muscle than men, theirs is about 50%. Body water declines throughout life, ultimately comprising about 45% of total body mass in old age.
