Question

The function f(t)=|98.6-x|, represents a persons variance from normal body temperature, where x represents a persons current body temperature in degrees Fahrenheit. Medical professionals says healthy individuals should have a variance of no more than 0.5 degrees Fahrenheit

Answer 1

Answer:

Step-by-step explanation:

Given the various variance of normal body temperature expressed by the function f(t) = |98.6-x| where x is persons current body temperature in degree Fahrenheit.

If medical professional says that healthy individual cannot have a variance of no more than 0.5F, we can get the variance by substituting x = 0.5 into the modeled function as shown;

Note that the function can either be negative or positive because of the modulus sign

If x = 0.5

For positive value,

f(0.5) = 98.6-0.5

f(0.5) = 98.1

If the function is negative

f(0.5) = -(98.6-0.5)

f(0.5) = -98.6+0.5

f(0.5) = -98.1

The variance for healthy individual will be expressed as -98.1≤f(x)≤98.1
