i) Predict whether the functions in each pair are equivalent by testing three different values of x. (3 marks each - show your work)

Question

ii) Determine whether the functions in each pair are equivalent by simplifying the expression on the right side. (2 marks each = show your work)

a)f(x)=-3(x+2)^2-(x+1), g(x)=(-3x^2)-(13x)-(13)

b) f(x)=(x^2-x-2)/(3x^2+4x+1), g(x)=(x-2)/(3x+1)

Answer 1

So, can you not just plug in some values and check the results? I'll show you my work if you'll show me yours...

Note: Usually it's easiest to use -1,0,1 for checking stuff.
