looking for math help

[Groffirl]

Hello, guys. I need help with this - On what interval f(x) = 6x + 54x - 9 concave up and down?
Is there any chance that someone have some math skills, and can give me a few tips?

I think there is something wrong with the question?

in the case 6x + 54x - 9 it is a linear function, with x = 0.15

cannot have concave and convex is a one-variable linear function


... or maybe I'm so rusty that I don't understand
