Q:

CalculusThe following curve passes through (3,1)Using linear lineralization

Accepted Solution

A:
Answer:Option 1.1Step-by-step explanation:The linearization of a curve implies the use of calculus to find the local value for the derivative and approximating the function by the use of the formula [tex]F(x) \approx F(x_0) + F'(x_0)(x-x_0)[/tex]The function is given in such way that it's much easier to find the derivative by implicit differentiation than isolating any of the variables [tex]2x^2y+y=2x+13[/tex]Differentiating with respect to x, we have [tex]4xy+2x^2y'+y'=2[/tex] Computing y' in the given point (3,1) we have 4(3)(1)+2(9)y'+y'=2 [tex]y'=\frac{2-12}{19}[/tex][tex]y'=-\frac{10}{19}[/tex]The function will be approximated with the expression [tex]F(x) = 1 -\frac{10}{19}(x-3)[/tex]To find the approximate value for x=2.8 [tex]F(2.8) = 1-\frac{10}{19}(-0.2)=1.1[/tex] The correct value is the option 1.1
