Best ResponseYou've already chosen the best response.0how would i go about solving this one...same way? For what value of the constant c is the function f continuous on (−∞,∞) where f(x)=...... cx+8 if x∈(−∞,2] ....... cx^2−8 if x∈(2,∞)......

Best ResponseYou've already chosen the best response.0hey so for the first problem...i used 4(3)1 = 11 and 5(3.1)+b = 15.5 + b. So I set 15.5 + b = 11 and I did the algebra and ended up with 4.5. what did i do wrong?

Best ResponseYou've already chosen the best response.04(3)=12 121=11 5(3)=15 so we have 11=15+b By adding 15 on both sides we get 26=b

For what value of the constant c is the function f continuous on (−∞,∞) where f(x)=...... cx+8 if x∈(−∞,2] ....... cx^2−8 if x∈(2,∞)...... once again i have to approach from both sides...if im approaching from left can I use x=1.5 and right x=3?

Best ResponseYou've already chosen the best response.0what no just before we plugged in 3 for both sides here we do 2
