# Function question watch

1. If f(x) is a real valued function such that 2f(x) + 3f(−x) = 15 − 4x, for every x ∈ R, what is the value of f(2)?

How do you solve this?
2. Stick x=2 and x=-2 in, try juggling that around?
2f(2) + 3f(-2) = 7
2f(-2) + 3f(2)= 23
then solve simultaneously
3. If you could also help me with this functions question please. Its a function inside a function which confuses me

4. m=1 n=1, sub into the third function set to return f(0,f(1,0)). F(1,0) = f(0,1) = 2
F(0,2) = 3, B

How do you solve the
f(0,f(1,0))

How do you solve the
f(0,f(1,0))
Firstly evaluate f(1,0)

Firstly evaluate f(1,0)
I got f(0,1) for that then what i do do i run it back through the function if so what line do i use

Yeah so what is f(0,1)?? Check the conditions in the piecewise function to determine what happens.

It is easier to lay it out step by step:
