Use a calculator to estimate the limit

b is correct.

Step-by-step explanation:

We are given a limit

Using calculator to find the value of limit.

First we check the limit exist or not.

We have to check left and right hand limit.

For Left hand limit, LHL

For Right hand limit, RHL

LHL=RHL=∞

Hence, b is correct.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
