FIND THE LIMITS BY CHART METHOD a lim x 3 x27x8x28x b lim x

Solution

a) lim x---> -3

x^2+7x-8/x^2+8x

using chart method

make a table with colums x and f(x)

x f(x)

-3.1

-2.9

-3.01

and check the values of f(x) it will move around a particular value....that is the value of the limit

b) lim x---> 0 x^2+5x/-x

same as above :)
