Answer:

(-9, 2]

Step-by-step explanation:

First, you have to find the interval that is the solution. Then you can write it using the appropriate notation.

-32 < 3x -5 ≤ 1

-27 < 3x ≤ 6 . . . . . . add 5

-9 < x ≤ 2 . . . . . . . . divide by 3

The open end of an interval is delimited using a curve bracket (parenthesis). The closed end of an interval is delimited using a square bracket.

This half-open interval will have a curved bracket on the left side, and a square bracket on the right side:

(-9, 2]

He should have added 1 to both sides to make the -1 on the right go to 0.
Then it would be 0 + m = -16 + 1 = -15
You can check your work by adding -1 and -15, which does in fact equal -16.
Hope this helped :)

If f(x) = <img src="https://tex.z-dn.net/?f=e%5E%7Bx%7D" id="TexFormula1" title="e^{x}" alt="e^{x}" align="absmiddle" class="lat

First we have to find derivative of f(x):

$f(x)=e^x \Rightarrow f'(x)=e^x$

For x=2 we have:

$f'(2)=e^2$

Now, $\ln f'(2)=\ln e^2 = 2$

Hence, the answer is A) 2
