Question

Match the function with its graph.

Answer 1

I am confused because:

g(x) = x^5-3x^2+1, a <0 makes the graph of choice 3
g (x) = x^3-3x^2+1, a>0 makes the graph of choice 3

f (x) = x^4-3x^2+1, a>0 makes the graph of choice 1
f (x) = x^6-3x^2+1, a<0 makes the graph of choice 1

Choices 1 and 3 look like it would go to + infinity
Choices 2 and 4 look like it would go to - infinity
