Answer:
Step-by-step explanation:
A function satisfying the equation 
is said to be an even function. This denomination comes from the fact that the same relation is satisfied for functions of the form 
with 
even. Observe that if 
is twice differentiable we can derivate using the chaing rule as follows:
implies 
Applying the chain rule again we have:
implies 
So we have that function 
is also an even function.
Answer: Yes, it means 3 times the square root of 2. First, find the square root of 2. Then multiply that value by 3. You can also type it into a calculator, and it will give you the exact value.
Answer:
25
Step-by-step explanation:
4/20 is 5 so 5*5 is 25 red candies

Answer:
y = -cos(x) -2
Step-by-step explanation:
Multiplying the function value by -1 reflects it across the x-axis. Adding -2 to the function value shifts it down by two units.
reflected: y = -cos(x)
then shifted: y = -cos(x) -2
