Hi There!
--------------------------------------
Function: g(x) = x³ + (x + 1)²
Substitute: -1
Substitute: g(-1) = -1³ + (-1 + 1)²
Remember to follow PEMDAS.
Parenthese's: g(-1) = -1³ + (0)²
Exponents: g(-1) = -1 + 0
Simplify: g(-1) = -1
--------------------------------------
Function: g(x) = x³ + (x + 1)²
Substitute: 1
Substitute: g(1) = 1³ + (1 + 1)²
Remember to follow PEMDAS.
Parenthese's: g(1) = 1³ + (2)²
Exponents: g(1) = 1 + 4
Simplify: g(1) = 5

Hope This Helps :)
