(or use the PAGE menu above to Print this page)

Use the worksheet to draw the combined graphs as described:

a) Sketch the __**sum function**__ y = f(x) + g(x), where math f(x)=\dfrac{1}{x+2} \text{ and } g(x)=-2x-1 math



b) Sketch the __**difference function**__ y = f(x) – g(x) where math f(x) = x^2-3 \text{ and } g(x) = |2x+1|-2 math



c) Sketch the product function y = f(x) × g(x) where math f(x) = 2 \sqrt{x+3}-1 \text{ and } g(x) =x-1 math
