Question

by putting x = - 2 in polynomial f(x) = 5x + 3, then the value of polynomial will be​

Answer 1

Answer:

$f(x) = 5x + 3 \\ x = - 2 \\ f( - 2) = 5( - 2) + 3 \\ f( - 2) = - 10 + 3 \\ f( - 2) = - 7$

Answer 2

Answer:

We will get the value of polynomial is-7.

Step-by-step explanation:

• As per the question we have to evaluate the given data.

       Given data:- x=-2.

       To find:- Value of f(x)=5x+3.

       Solution:-

• To solve the above question we will follow the BODMAS rule.

• BODMAS is an order of mathematic operations.

• It stands for,

           B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

       Now put the value of x=-2 in f(x)=5x+3.

         $f(x)=5x+3\\f(x)=5(-2)+3\\f(x)=-10+3\\f(x)=-7$
