Question

Graph f(x) = x + 2(x - 3) then use the graph to evaluate lim x->2 x + 2(x - 3)

Answer 1

@RadEn can you help :)

Answer 2

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.

Answer 3

okay and how would i evaluate after making the graph?

Answer 4

well you just have to find the value of f(x) for x=2. thats all it means.

Answer 5

umm so i should substitute the 2 in all the x's then solve?

Answer 6

Look on the graph at x = 2 and read off the value of y.

Answer 7

ohhh okay got you thanks

Answer 8

so it will be zero right? thats what i got
