Question 504050: if f(x+h)-f(x)OVER h and h cannot equal 0 how would i solve f(x)=-3x+10
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!

f(x) = -3x+10

f(x+h) = -3(x+h)+10

f(x+h) = -3x-3h+10

---------------------------------

[ f(x+h) - f(x) ]/h

[ (-3x-3h+10) - (-3x+10) ]/h

[ -3x-3h+10 +3x-10 ]/h

[ -3h ]/h

-3

So [ f(x+h) - f(x) ]/h = -3 where f(x) = -3x+10
