## Homework Statement

Find values for

*a*and

*b*that ensure

*f*is a continuous function if

f(x) = ax + 2b if x ≤ 0

x

^{2}+3a - b if 0 < x ≤ 1

2x - 5 if x > 1

## Homework Equations

## The Attempt at a Solution

ax + 2b = 2x -5 (when x = o)

2b = -5

b = -5/2

3a +5/2 = -3

a = -11/6

when i plug these a and b into the each equation i get

-5 as the answer for the first equation

-3 as the answer for the second equation

-5 as the answer for the third equation

why isnt the 2nd equation coming out to -5? i need them all to equal so they can be continuous. all the limits need to equal.
