Question
assume points P and Q are close. Estimate g(Q)

Transcribed Image Text:24. \( P = (30, 125), Q = (25, 135), g(P) = 840, g_x(P) = 4, g_y(P) = 1.5. \)

Transcribed Image Text:In this mathematical problem, the following points and functions are described:
- Point \( P = (60, 80) \)
- Point \( Q = (60.5, 82) \)
Functions and their values at point \( P \):
- \( g(P) = 100 \)
- \( g_x(P) = 2 \) (Partial derivative of \( g \) with respect to \( x \) at \( P \))
- \( g_y(P) = -3 \) (Partial derivative of \( g \) with respect to \( y \) at \( P \))
This information is often used in calculus or multivariable functions to describe rates of change of the function \( g \) at specific points.
