Answer:
y=[x+1]-3 because it's at the end of the line
To find the inverse, interchange the variables and solve for y.
f^−1(x)=−25+5x/2
Remark
I didn't know this was a calculus question. How dumb of me.
f(x + h) - f(x)
==========
x + h - h
50/6 - 51/6 =( -1/6+ h)/h
The h's will disappear when the limit is taken.
answer - 1/6 which is A. If anyone else answers take their answer.
The length of side A is 194
