Answer:
88
Step-by-step explanation:
PEMDAS
9*(6+7-3)-2
1) 6+7=13
13-3=10
9*10-2
2)9*10= 90

Answer:
f(x)=x^2
Step-by-step explanation:
if you wanted have a function where both of the robot's arms are in the air the function could be x to the power of any even number such f(x)=x^2, f(x)=x^4, f(x)=x^6, or even f(x)=x^10. And you could still do the same transformations with these equations.
