Find the linearization of the function at a . f(x) = x 4 + 3 x2    , a = -1

Let f(x) be the height of a maple tree in inches and the number of years since 2000. A linear model for the data is f(x) = 9.44x + 84.182. 220 210- 200 190 180 170 160 150- 140- 130- 120 110 100 -90- ge 70- -60 -50+ 3 Ő 9 12 A) To the nearest inch, estimate the height of the maple tree in 2013. inches B) Use the equation to find the year in which the tree will be 250 inches tall.

Determine if the set of functions is linearly independent

Let f be a function that satisfies f(1, 2) = 16, f(1, 2) = -4, and f,(1, 2) = -3. Use linearization to estimate the value f(1.01, 1.98). f(1.01, 1.98) x

The functions f(x) = x-1 and g(x) = 2-2x are linearly dependent. Justify your Answer T F
