# In Problems 45-48, use the table feature of a graphing calculator to predict each limit. Check your work by using either a graphical or an algebraic approach. lim x → 7 f ( x ) where f ( x ) = { 2 + − x 2  if  x ≤ 7 13 − 9 x  if  x  > 7

To determine

To calculate: The value of limx7f(x), using the TABLE feature of calculator. Also, check the limit.

Explanation

Given Information:

The limit is limx7f(x). The function is f(x)={2+xx2      if x7139x          if x>7.

Calculation:

Consider the provided limit,

limx7f(x)

Where the function, f(x), is

f(x)={2+xx2      if x7139x          if x>7

Use the ti-83 graphing calculator for its TABLE feature.

Step 1: Open the ti-83 graphing calculator.

Step 2: Press the [Y=] key and enter the function in Y1, Y1=2+xx2.

Step 3: Press the [2nd] key then the [WINDOW] key and adjust the values accordingly.

Step 4: Press the [2nd] key and then the [GRAPH] key.

 X Y1 6.4 −32.56 6.5 −33.75 6.6 −34.96 6.7 −36.19 6.8 −37.44 6.8 −38.71 6.9 −40 X=6.4

Step 5: Press the [Y=] key and enter the function in Y2, Y2=139x.

Step 6: Press the [2nd] key then the [WINDOW] key and adjust the values accordingly.

Step 7: Press the [2nd] key and then the [GRAPH] key.

 X Y2 7 −50 7.1 −50.9 7.2 −51.8 7.3 −52.7 7.4 −53.6 7.5 −54
