a.
Do the functions f(x) = x²+5x+6 and g(x) = x + 2 have the same graph? Does
x2+5076 =x+2? Why or why not?
x+3
x+3
b. The expressions x2-5x+6 and x-3 are not quite equivalent. Add a statement to
x-2
x²
2-5x+6 = x-3 to make it true.
x-2
c.
From now on, domain restrictions will be important. Rewrite h(x)=x²-4 and include
any necessary domain restrictions.
