to determine the intervals where a function is concave up and concave down, the first step is to find all the x values where (select all that are needed):\n○f(x)=0\n○f(x) is undefined\n○f(x)=0\n○f(x) is undefined\n○f(x)=0\n○f(x) is undefined

Answer

Brief Explanations:

To find intervals of concavity (concave - up and concave - down) of a function, we first find the inflection points. Inflection points occur where the second - derivative (f''(x)=0) or where (f''(x)) is undefined. So, we need to find the (x) - values where (f''(x) = 0) and where (f''(x)) is undefined.

Answer:

(f''(x)) is undefined, (f''(x)=0)
