given,
f(x)=x^2 +2
now
f(-x)=(-x)^2 +2 = x^2 +2= f(x)
since f(-x)=f(x)
the given function is even
Using Pythagoras theorem :
C = sqrt(a^2 + b^2)
C = sqrt(36+64)
C = sqrt(100)
C = 10 feet
b=5, commutative property
c=3, associative property
Answer: Here are a few ways that you could apply expressions or equations to a camping trip.
The cost of renting a cabin could be: C = 50N + 70, where C is the cost and N is the number of nights.
The number of tents needed could be: T = P/3, where T is the number of tents and P is the number of people going.
The amount of marshmallows needed could be: M = 5P, where M is the number of marshmallows and P is the number of people.
