## Homework Statement

Consider the function f(x) = { ax^2 + b if x >= 1

4 - x if x<1

for which values of a and b does this function have a derivative at 1?

## Homework Equations

## The Attempt at a Solution

Can someone explain to me what the question wants? does it ask for the values of a and b that will make the derivative of ax^2 + b equal the derivative of 4 - x ?

I'm so lost
