Step 1 :Given the following table, give the best estimate for \(f^{\prime}(9)-f(9)\)
Step 2 :\[\begin{array}{ccccccc}x & 0 & 3 & 6 & 9 & 12 & 15 \\f(x) & 35 & 45 & 54 & 61 & 29 & 7\end{array}\]
Step 3 :To estimate \(f^{\prime}(9)\), we can use the difference quotient formula, which is \(\frac{f(x+h)-f(x)}{h}\), where \(h\) is a small number. In this case, we can use the points \(x=6\) and \(x=12\) to estimate \(f^{\prime}(9)\), so \(h=3\).
Step 4 :Then, we can calculate \(f^{\prime}(9)-f(9)\).
Step 5 :\(f^{\prime}(9) = -8.333333333333334\)
Step 6 :\(f(9) = 61\)
Step 7 :\(f^{\prime}(9)-f(9) = -69.33333333333333\)
Step 8 :Round your answer to the nearest tenth.
Step 9 :Final Answer: The best estimate for \(f^{\prime}(9)-f(9)\) is \(\boxed{-69.3}\).
