A linear function is a polynomial function of degree 1 (1,2,3,4,5,6,....) A quadratic function is a polynomial function of degree 2 (1,4,9,16,25,49,64,81,...) A exponential function is not a polynomial function (we may imagine a infinity degree) (1,2,4,8,16,32,64,128,256,512,1024,...)
In general, time is not a function of temperature, but this could depend on the problem you're solving. For example, imagine a ball of metal cooling down, and data was given on how long the ball was cooling down and the temperature at the center. Someone could have fit a curve or function to the temperature to show how much time has elapsed when inputting temperature as the independent variable.
By definition it is known that speed equals the distance between time. Therefore, according to the definition, the last two options are the possible answers: Let's evaluate the third option: y = (3/2) * (1 / x) x = 12 y = (3/2) * (1/12) = 3/24 = 1/8 The table is not fulfilled Let's evaluate the fourth option: y = (96 / x) x = 12 y = (96/12) = 8 Yes, the table is met. answer: y = (96 / x)
