For 11, we start by plugging 1 in, getting 2(1)^2+1-5=-2=y
Plugging 1+m instead, we get 2(1+m)^2+1+m-5=2(1+2m+m^2)+1+m-5
= 2+4m+2m^2+1+m-5= 2m^2+5m-2. We have to find the difference between that and -2, so 2m^2+5m-2 -(-2)=2m^2+5m
Differentiating 12, we use the Power Rule to get -6x^2+14, and plugging x=1 into it, we get -6(1)^2+14=-6+14=18

(I don't know if this is correct or not, if so i'm glad i helped!)
9 1/8
4/8+5/8=9/8=1 1/8
5+3=8
8+1 1/8=9 1/8
A) 15.20
b) 965.2
i hope this is right (^^)
