Basic concepts: Adding and subtracting polynomials, Function notation, Function notation (Advanced), Operations with functions,

adding functions: $(f+g)(x) = f(x)+g(x)$

- 1.
**Determine the Sum of Two Functions Algebraically**

If $f(x)= 5x^3-x+6$ and $g(x)=4x-8$, determine:a)$(f+g)(x)$b)$(f+g)(2)$, evaluate in two different ways - 2.
**Determine the Sum of Two Functions Graphically**

Given the graphs of functions $f(x)$ and $g(x)$

a)sketch: $(f+g)(x)$b)evaluate:

i) $(f+g)(-5)$

ii) $(f+g)(0)$

iii) $(f+g)(5)$ - 3.
**Determine the Value of a Combined Function**

If $f(x)=\sqrt{2x}-1$ and $g(x) = -|6-x|$

Evaluate: $5(f+g)(8)-10$
