1. How do you find the linearization of f(x) at x = a? Illustrate with a concrete example
We want to estimate f(1.01 , 0.97) for the function f(x,y)= √(4 - x2 - y2). For this, we can use an appropriate linearization of the function f(x,y).Then Fx (1,1) = ? and Fy (1,1) = ? therefore we can estimate the mentioned value obtaining an answer of f( 1.01 , 0.97) ≈ L( 1.01, 0.97) =
Finad the linearization at the given points. f(x)= 6/x^2 at (2, 3/2)
Consider an experiment in which a subject performs a task while being exposed to two different stiumli (for example, sound and light). For low levels of the stimuli, the subject's performance might actually improve, but as the stimuli increase, they eventually become a distraction and the performance begins to deteriorate. Suppose in a certain experiment in which x unites of stimulus A and y unites of stimulus B are applied, the performance of a subject is measured by the funtion f(x,y) = C+xye(1-x^2-y^2) where C is a positive constant. How many units of each stimulus result in maximum performance?

Consider the general equation of a quadratic function: f(x)=ax2+bx+cf(x)=ax2+bx+c (Recall: aa, bb, and cc represent constants). Use the derivative f′(x)f′(x) to find the critical value of f(x)f(x) in terms of aa and bb (does this formula look familiar?) Use the second-derivative test to show that the critical value is a local maximum if a<0a<0 or a local minimum if a>0a>0. What determines whether the graph of f(x)f(x) is concave up or concave down? Does the graph of f(x)f(x) have any inflection points? Explain.
