Domain of f(x)=(3x+4)/(x2+9)
What is (-infinity, infinity)
Find fog(x) if:
f(x)=3x-5
g(x)=2-x2
What is -3x2+1
The maximum value of the graph of the following:
-(x-3)2+7 for x>0
f(x) = {
-lx+3l for x<=0
What is 7
alternative answer: What is (3,7)
The multiplicity of the largest zero from the following function:
g(x)= -x(x2+3)(x-2)5
Also indicate if that multiplicity is going to cross at the x-axis or bounce off.
The zero is x=2. The multiplicity is 5.
It will cross at x=2 because the multiplicity is odd.
