average rate of change is just the slope from (0,f(0)) to (2,f(2))
basically, average rate of change=slope=
evalaute each
f(2)=4(2)^2=4(4)=16
f(0)=4(2)^0=4(1)=4
so average rate of change=
average rate of change is 6
The correct answer is C.
If our equation is y=x+2, the fact that there is no number attached to x means that there is a slope of 1.
Since we are doubling the slope, we would multiply 1 by 2.
1*2=2.
Our equation is now y=2x+2.
I also says to divide the y intercept by 2. The y intercept is the +2 after the x, so divide 2 by 2.
2/2=1
Our equation is now y=2x+1
