If f(x)=|2x+1| and g(x)=x-4, find f(g(1)) and g(f(1))
and
Find the equation of the linear function f if f(1)=-1 and f(4)=8
Thank you for looking it over,any help is greatly appreciated..
. Now evaluate at .
The other composite is similar.
Oh. I just notice the second half of the problem. To find an equation to a line given 2 points in the plane, simply make use of the point-slope form of a line,
where - in your case -
