# Continuous f(x) problem

Continuous f(x) problem
f(x) = ( .75x+13, x < -8 )
( x^2 + bx + c, -8<x<-3 )
( 4x + 9, -3 < x<2 )
(x^2 + ax+ b, x > 2 )

Can someone tell me how to go about solving this problem? I am really stuck. All help would be appreciated. You must solve for a,b, c.

Do you know what a piecewise function is?

apparently he wants to find b so that the function is continuous

you need to say what you want Da Freak, we're not mind readers
