Answer:
an open circle on -1.3 on the line and draw a line to the right with an arrow.
Step-by-step explanation:
On your number line, draw an open circle on -1.3 and then draw a line on the number line going to the right and ending with an arrow at the end. The open circle means that it is that starting point, but is not equal to it.

in exponent form and in word form it is 10 to the 5th power
Use the chain rule to compute the second derivative:

The first derivative is


Then the second derivative is


Then plug in π/4 for <em>x</em> :

Rewrite the limit as

Then both numerator and denominator approach infinity (with different signs, but that's not important). Applying L'Hopital's rule, we get
