- f:[0,1] -> [0,1] such that f(x)=x^2 has two fixed points. Is this true?Finad the linearization at the given points. f(x)= 6/x^2 at (2, 3/2)At the end of the exam, all of a sudden your calculator breaks down. All you have left to do is to compute the value at (2.95,12.2) of the function f(x,y) = √xy, rounded to two decimals. You decide to put to work what you have learned in the math course: • You note that f (3, 12) = 6 and that (2.95, 12.2) is close to (3, 12).• You use the linear approximation of the function f at the point (3, 12) to compute an approxi- mate value for f (2.95, 12.2).• Is your rounded outcome on the exam correct?

Find the equation for L2 in form of y=mx+cA certain country uses a progressive tax system. The amount of tax consists of a linear part proportional to the income and a nonlinear part depending on the income by a power law. The total amount of tax is determined by the formula T(W)=aW+(bW+c)p, where W is the income; p is the exponent, a,b,c are some positive numbers.
