The answer is $10 because 123=$6 and 4 hours is =$4 6+4=10
Answer: -x^2 + 12x +5
Step-by-step explanation:
Answer:
"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, where all you have to do is simplify; that is more of an order-of-operations kind of question
example: So let we are given a polynomial function as:
and we are aksed to evaluate this polynomial at ![x=-3](https://tex.z-dn.net/?f=x%3D-3)
Then the value of the polynomial will be:
![f(-3)=(-3)^4+3\times (-3)^3-(-3)^2+6\\\\f(-3)=81+3\times (-27)-9+6\\\\f(-3)=81-81-9+6\\\\f(-3)=-3](https://tex.z-dn.net/?f=f%28-3%29%3D%28-3%29%5E4%2B3%5Ctimes%20%28-3%29%5E3-%28-3%29%5E2%2B6%5C%5C%5C%5Cf%28-3%29%3D81%2B3%5Ctimes%20%28-27%29-9%2B6%5C%5C%5C%5Cf%28-3%29%3D81-81-9%2B6%5C%5C%5C%5Cf%28-3%29%3D-3)
Hence on evaluating the polynomial function f(x) at
we get the value of the polynomial function as
