Solve the Polynomial Equation Models the Age in Human Years $\mathrm { H } ( \mathrm { x } )$

question 155

Multiple Choice

Solve the polynomial equation. In order to obtain the first root, use synthetic division to test the possible rational
roots.
-The polynomial function
$$\mathrm { H } ( \mathrm { x } ) = - 0.001183 \mathrm { x } ^ { 4 } + 0.05495 \mathrm { x } ^ { 3 } - 0.8523 \mathrm { x } ^ { 2 } + 9.054 \mathrm { x } + 6.748$$
models the age in human years, $\mathrm { H } ( \mathrm { x } )$ , of a dog that is $x$ years old, where $x \geq 1$ . Using the graph of this function shown below, what is the approximately equivalent dog age for a person who is 60 ?

• A) 11 years
• B) 9 years
• C) \(8.5\) years
• D) \(12.5\) years
