Graph f(x) = x + 2(x - 3) then use the graph to evaluate lim x->2 x + 2(x - 3)
so f(x)= 3x - 6. or y=3x-6. take any 3 values of x and find values of y for them. plot and join the points on the cartesian plane and you have the graph which is a straight line.
okay and how would i evaluate after making the graph?
well you just have to find the value of f(x) for x=2. thats all it means.
umm so i should substitute the 2 in all the x's then solve?
Look on the graph at x = 2 and read off the value of y.
ohhh okay got you thanks
so it will be zero right? thats what i got
