Consider the following points: $$(5,8), \quad(3,6), \quad(-6,-9), \quad(-1,-4), \quad(-10,7)$$ Could these points all be on the graph of a function \(y=f(x) ?\)
The loudness \(d\) (in decibels) is given by the equation $$d(I)=10 \cdot \log _{10}\left(\frac{I}{I_{0}}\right)$$ where \(I\) is the given intensity and \(I_{0}\) is the threshold sound (the quietest detectable intensity). Determine \(d^{-1}(85)\) in terms of the threshold sound.
The value \(v\) of a car in dollars after \(t\) years of ownership can be modeled by $$v(t)=10000 \cdot 0.8^{t}$$ Find \(v^{-1}(4000)\) and explain in words what it represents.
Let \(f(x)=x+1\). What is \(f(f(f(f(1)))) ?\)
Consider the following points: $$(7,-4), \quad(0,3), \quad(-2,-2), \quad(-1,-8),$$ Could these points all be on the graph of a function \(y=f(x) ?\)
