Q. Which of the following is a solution to the inequality below?

\newline

s \leq 4

\newline

Choices:

\newline

(A)

s = 3

\newline

(B)

s = 8

\newline

(C)

s = 10

\newline

(D)

s = 12

Understand the inequality: Understand the inequality. $\newline$ The inequality $s \leq 4$ means that the value of $s$ must be less than or equal to $4$ .
Evaluate choices: Evaluate each choice to see if it satisfies the inequality. $\newline$ Start with choice (A) $s = 3$ . $\newline$ Check if $3 \leq 4$ . $\newline$ Since $3$ is less than $4$ , $3 \leq 4$ is true.

Question

g(x)=5-e^{x}

\newline

Below is Sean's attempt to write a formal justification for the fact that the equation

g(x)=0

has a solution where

1 \leq x \leq 4

\newline

Is Sean's justification complete? If not, why?

\newline

Sean's justification:

\newline

g

Amrita's justification:

\newline

Polynomial and trigonometric functions are differentiable and continuous at all points in their domain, and

[-1,4]

g^{\prime}

s domain. Also,

\newline

\begin{array}{l} g(-1)=-1 \text { and } \\ g(4)=1 \text {, so } \\ \frac{g(4)-g(-1)}{4-(-1)}=0.4 . \end{array}
