Answer :
The value of the expression (h ⁰ g) ( -1) = 50
In arithmetic, an expression or mathematical expression is a finite mixture of symbols that is well-shaped in keeping with rules that rely upon the context. We write an expression in math with the aid of using numbers or variables and mathematical operators which are addition, subtraction, multiplication, and department. For instance, the expression of the mathematical statement "four delivered to 2", might be 2+4.
To solve the expression use the following steps:
g ( x ) = 5x - 2 h ( x ) = x^2 + 1
g ( - 1 ) = 5 ( - 1 ) - 2 = - 7
( h ⁰ g ) ( -1 ) = h ( g ( - 1 ) = h ( - 7 )
h ( -7 ) = ( -7 )^2 +1 = 49 + 1 = 50
( h ⁰ g ) ( -1 ) = 50
An expression in math is a sentence with at the very least two numbers or variables and at the least one math operation. This math operation can be addition, subtraction, multiplication, or department. The shape of an expression is: Expression is (quantity/variable, Math Operator, quantity/variable).
