Answer 2

Looking for concavity relies on using the second derivative.

Answer 3

So you're looking for \(f''(x)\)

Answer 4

but i dont have an equation to find the derivative of the graph

Answer 5

use this chart, it will help you understand concavity and derivatives.

Answer 6

Thank u so much for the chart! then i think its C, concave up on (-1, infinity) :)

Answer 7

Mmhmm
