Please help answer my question! It will be greatly appreciated!

Function: f(x)=x3+0.8x21.4x0.579

The equation of the tangent line, in slope-intercept form, tothe above function at the point(0.3,f(0.3)):y=0.65x0.705

A storm is brewing, so a scientist at the McMurdo Station in Antarctica begins monitoring the outdoor temperature. Suppose the function f(x)given above represents the outdoor temperature in Fahrenheitx hours after the scientist begins monitoring. We knowf(0.3)is the slope of the tangent line tofat the point(0.3,f(0.3)). However, what is the real-world interpretation off(0.3)in the context of this application question, and what would the unit of measure be?
