A function calculates an output based on the definition of the function and the input.
-
a) 4; b) 17; c) 0 (zero is an even number because it is divisible by 2 without a remainder)

A function is calculating a value (output) that is dependent on one or more variables (input). A function always follows a pre set formula.
a) f(2) (x is even) means the formula is f(x) = x^2 and that gives us f(2) = 2^2 = 4 Answer: 4
b) f(7) (x is odd) means the formula is f(x) = x +10 and that gives us f(7) = 7 +10 = 17 Answer: 17
c) f(0) (x is even) means the formula is f(x) = x^2 and that gives us f(0) = 0^2 = 0 Answer: 0
- f(x) = (x/4) - 5

#Written in Python since that is
#the programming language that I am most familiar with.
def f(x):
if (x % 2 == 0): # if x divided by 2 leaves no remainder...(x is even)
return(x**2) # return x to the power of 2
else:
return x+10 # otherwise (x is odd) return x + 10
# What will be the outputs of the following inputs?
print(f(2)) # 14
print(f(7)) # 17
print(f(0)) # 0

1.In my understanding function is a math formula. And u are able to change variable in a function, not in a formula. Output depends on a formula(captain obvious) and the variable(input).
2.f(x) = {x^2 if x is even x+10 if x is odd}
f(2)=4
f(7)+17
f(0)=0
- f(x)=(x/4)-5
it toked me like 20 min to remember what a function is and how to use it. thanks for school…
