Question

Which is a graph of the following
f(x) = [x³ if x ≤0] [ex if x > 0]

Answer 1

a

Explanation:

c is not a function, so eliminate it.

When x=0, the function is not continuous, so eliminate b.

Since the function is x³ for
`x\leq 0`, there should be an open circle from the right and a closed circle from the left.
