Full solution

Q. Find the slope of the tangent line to

g(x) = x

at

x = 19

.

\newline

Write your answer as an integer or a fraction. Simplify any fractions.

\newline

____

\newline

Identify Function and Point: Identify the function and the point where the slope is needed. $\newline$ Function: $g(x) = x$ $\newline$ Point: $x = 19$
Determine Derivative of Function: Determine the derivative of $g(x)$ , since the derivative represents the slope of the tangent line at any point $x$ . Derivative of $g(x)$ = $1$ (since the derivative of $x$ with respect to $x$ is $1$ )
Evaluate Derivative at $x = 19$ : Evaluate the derivative at $x = 19$ to find the slope of the tangent line at that point. $\newline$ Slope at $x = 19$ = $1$ (since the derivative is constant and equals $1$ )
